Una herramienta basada en MCP (Protocolo de Control de Modelos) para consultar y usar la API GraphQL de GitHub. Este proyecto proporciona un servidor que permite explorar el esquema GraphQL de GitHub y ejecutar consultas GraphQL mediante herramientas cliente MCP (como Claude AI).
La API GraphQL de GitHub ofrece ventajas significativas sobre las API REST tradicionales:
Recuperación precisa de datos : GraphQL permite a los clientes especificar exactamente qué campos necesitan, evitando el exceso de datos.
Consumo de tokens reducido : al solicitar solo los campos necesarios, el tamaño de la respuesta de la API se reduce significativamente, lo que disminuye el consumo de tokens del modelo de IA.
Solicitud única de datos relacionados : una consulta puede recuperar varios recursos relacionados, lo que reduce la cantidad de solicitudes
Autodocumentación : a través de su sistema de documentación integrado, puede consultar y comprender directamente el esquema de API sin documentación externa.
Sistema de tipos fuerte : proporciona verificación de tipos, lo que reduce errores
Este proyecto aprovecha estas ventajas para proporcionar herramientas que lo ayuden a explorar de manera efectiva el esquema de API GraphQL de GitHub y ejecutar consultas optimizadas, proporcionando a los asistentes de IA capacidades eficientes de recuperación de datos de GitHub.

A tool to execute GitHub GraphQL API queries. Before using, it's recommended to check the documentation first, and include ID fields in your queries for easier follow-up operations Args: graphql: The GraphQL query Returns: str: Execution result
| Name | Required | Description | Default |
|---|---|---|---|
| graphql | Yes |
| Name | Required | Description |
|---|---|---|
| result | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions checking documentation and including ID fields, which adds some operational context, but fails to address critical traits like authentication requirements, rate limits, error handling, or mutation vs. query behavior. For a GraphQL API tool with zero annotation coverage, this leaves significant gaps in understanding how the tool behaves in practice.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is appropriately sized and front-loaded, starting with the core purpose and usage recommendation in the first sentence. The Args and Returns sections are structured but could be more integrated. There's minimal waste, though the 'Returns: str: Execution result' is redundant given the output schema, slightly reducing efficiency.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (GraphQL API execution) and the presence of an output schema (which handles return values), the description is partially complete. It covers basic purpose and some usage tips but lacks details on authentication, error cases, or integration with sibling tools. Without annotations and with low schema coverage, it doesn't fully equip an agent for reliable tool invocation in a GitHub context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds minimal meaning beyond the input schema: it names the single parameter 'graphql' and states it's 'The GraphQL query', which the schema already indicates as a string type. With 0% schema description coverage, the description doesn't compensate by explaining query syntax, validation rules, or examples. The baseline is 3 because the schema covers the parameter's existence and type, but the description fails to enhance understanding significantly.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose as 'execute GitHub GraphQL API queries' with a specific verb (execute) and resource (GitHub GraphQL API queries). It distinguishes itself from sibling tools like graphql_schema_root_type and graphql_schema_type by focusing on query execution rather than schema exploration. However, it doesn't explicitly contrast with print_type_field, leaving some sibling differentiation incomplete.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides implied usage guidance by recommending checking documentation first and including ID fields for follow-up operations, which suggests context for when to use this tool effectively. However, it lacks explicit when/when-not criteria or named alternatives to sibling tools, leaving the agent to infer optimal usage scenarios without clear boundaries.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
A tool to query GitHub GraphQL schema root types. You need to provide the root type name (QUERY/MUTATION) Args: type_name: root type (QUERY or MUTATION) Returns: str: Documentation content
| Name | Required | Description | Default |
|---|---|---|---|
| type_name | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but offers minimal behavioral context. It states the tool returns documentation content as a string but doesn't disclose authentication requirements, rate limits, error handling, or what specific documentation format to expect. The 'query' verb implies read-only, but this isn't explicitly confirmed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is appropriately sized with three sentences: purpose statement, parameter guidance, and return value. It's front-loaded with the core function. Minor improvements could include bullet points for Args/Returns, but overall it's efficient with minimal waste.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with no annotations, no output schema, and low schema coverage, the description is incomplete. It lacks details on authentication, error cases, the structure of returned documentation, or how this integrates with sibling tools. The return type 'str: Documentation content' is vague without examples or format specifications.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, but the description compensates by explaining that 'type_name' should be 'QUERY or MUTATION' and represents the 'root type name.' This adds meaningful context beyond the schema's generic 'Type Name' title, though it doesn't detail format constraints or examples.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose as 'query GitHub GraphQL schema root types' with specific resource (GitHub GraphQL schema) and verb (query). It distinguishes from sibling 'graphql_schema_type' by focusing on root types only, though it doesn't explicitly contrast with 'call_github_graphql' or 'print_type_field'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like 'graphql_schema_type' for non-root types or 'call_github_graphql' for actual queries. The description mentions needing to provide root type name but doesn't explain use cases or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
A tool to query specific type documentation in GitHub GraphQL schema. You need to provide the type_name
Args:
type_name: Type name like SecurityAdvisoryConnection
Returns:
str: Documentation content
| Name | Required | Description | Default |
|---|---|---|---|
| type_name | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool queries documentation, implying a read-only operation, but doesn't specify if it's safe, requires authentication, has rate limits, or what happens on errors. For a query tool with zero annotation coverage, this leaves significant behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is appropriately sized and front-loaded: the first sentence states the purpose clearly. The 'Args:' and 'Returns:' sections are structured but slightly redundant with the schema. It's concise with no wasted words, though the formatting could be more integrated.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's low complexity (1 parameter, no output schema, no annotations), the description is somewhat complete but has gaps. It covers the basic purpose and parameter semantics but lacks usage guidelines, behavioral details, and output explanation. For a simple query tool, it's adequate but not fully comprehensive.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema description coverage is 0%, so the description must compensate. It explains the single parameter 'type_name' as 'Type name like `SecurityAdvisoryConnection`,' adding meaning beyond the schema's basic 'string' type. This clarifies the parameter's purpose and provides an example, though it could be more detailed about valid type names or constraints.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'query specific type documentation in GitHub GraphQL schema.' It specifies the verb ('query'), resource ('type documentation'), and domain ('GitHub GraphQL schema'). However, it doesn't explicitly differentiate from sibling tools like 'graphql_schema_root_type' or 'print_type_field' beyond mentioning 'specific type' documentation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides minimal guidance: 'You need to provide the type_name' and gives an example ('SecurityAdvisoryConnection'). It doesn't explain when to use this tool versus alternatives like 'graphql_schema_root_type' or 'print_type_field,' nor does it mention prerequisites or exclusions. The guidance is basic and lacks context for tool selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
A tool to query GitHub GraphQL schema root type fields. You need to provide root_type_name and type_fields_name
Args:
type_name: root type like QUERY or MUTATION
type_fields_name: field name like repository based on root type documentation
Returns:
str: Documentation content for the specified field
| Name | Required | Description | Default |
|---|---|---|---|
| type_name | Yes | ||
| type_fields_name | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It discloses that the tool returns documentation content as a string, which is useful behavioral information. However, it doesn't mention whether this is a read-only operation, what happens with invalid inputs, if there are rate limits, authentication requirements, or error behavior. For a query tool with zero annotation coverage, this leaves significant behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is reasonably concise but has structural issues. The first sentence clearly states the purpose, but the parameter explanations are formatted as 'Args:' and 'Returns:' sections which are somewhat redundant with the schema. The information is front-loaded but could be more efficiently integrated. It's not excessively verbose but has minor organizational inefficiencies.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 2 parameters with 0% schema coverage and no output schema, the description provides adequate parameter semantics and specifies the return type as a string. However, it doesn't explain the format of the returned documentation content, error conditions, or authentication requirements. For a query tool with no annotations, this is minimally complete but lacks depth about operational behavior and integration context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It provides meaningful semantics for both parameters: 'type_name' is explained as 'root type like `QUERY` or `MUTATION`' and 'type_fields_name' as 'field name like `repository` based on root type documentation'. This adds substantial value beyond the bare schema, though it doesn't provide exhaustive examples or format details. With 2 parameters fully addressed, this exceeds the baseline expectation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'query GitHub GraphQL schema root type fields' with specific verbs ('query') and resources ('GitHub GraphQL schema root type fields'). It distinguishes from siblings like 'call_github_graphql' (which executes queries) and 'graphql_schema_type' (which might query non-root types), but doesn't explicitly contrast them. The purpose is specific but sibling differentiation is implied rather than explicit.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It mentions 'based on root type documentation' but doesn't specify when this tool is appropriate compared to sibling tools like 'graphql_schema_root_type' or 'graphql_schema_type'. There are no explicit when/when-not instructions or named alternatives, leaving usage context unclear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Recent tool additions, removals, and schema changes observed during successful MCP inspections. Dates show when Glama detected each change.
call_github_graphqlgraphql_schema_root_typegraphql_schema_typeprint_type_fieldThe tools have overlapping purposes focused on GitHub GraphQL schema exploration, which could cause confusion. call_github_graphql is distinct for executing queries, but graphql_schema_root_type, graphql_schema_type, and print_type_field all retrieve schema documentation with subtle differences in scope (root types vs. specific types vs. root type fields). Descriptions help clarify, but an agent might struggle to choose between them for schema inspection tasks.
Tool names follow a consistent snake_case pattern with clear verb_noun structure (e.g., call_github_graphql, graphql_schema_type). Minor deviations exist, such as graphql_schema_root_type using 'root_type' while print_type_field uses 'type_field', but overall the naming is predictable and readable across all tools.
With 4 tools, the count is reasonable for a GitHub GraphQL API server, providing a focused set for query execution and schema exploration. It's slightly thin for comprehensive API coverage but well-scoped for its intended purpose, avoiding bloat while supporting core workflows like querying and schema lookup.
The tool set covers query execution and schema documentation retrieval, but has notable gaps for a GitHub API surface. It lacks CRUD operations for resources like repositories, issues, or pull requests, and doesn't support mutations or advanced query building. Agents can work around this by crafting GraphQL queries, but the surface is incomplete for typical GitHub automation tasks.
