TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover safety hints (readOnly, destructive). The description adds engine detail (Prince) and default filename, but does not disclose return value or file output behavior. While output_filename suggests file creation, readOnlyHint=true is not directly contradicted, so no contradiction is flagged.
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 front-loaded with a one-line purpose followed by a structured Args list. Every line contributes value, with no redundancy or filler.
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 7 parameters, no output schema, and only base annotations, the description should explain return behavior and side effects. It does not mention where the PDF is written or what is returned. It also lacks notes on limitations or integration with sibling tools, leaving noticeable gaps.
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 descriptions are absent (0% coverage), so the description must compensate. It explains all parameters with concise purposes, examples for page_size and page_margin, and default for output_filename. However, values for pdf_profile and page_size are not fully enumerated.
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 'Convert HTML content to PDF using Prince', specifying both input and output, and naming the engine. This distinguishes it from siblings like markdown_to_pdf and url_to_pdf.
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 implies use when HTML content needs conversion to PDF, but does not explicitly mention alternatives or when-not-to-use scenarios. Context is clear but exclusions are absent.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
markdown_to_pdfARead-onlyInspect

pdf_profile: PDF profile (e.g., PDF/A-3b, PDF/UA-1)
output_filename: Output filename for the PDF (default: "output.pdf")
| Name | Required | Description | Default |
|---|---|---|---|
| style | No | ||
| content | Yes | ||
| page_size | No | ||
| javascript | No | ||
| page_margin | No | ||
| pdf_profile | No | ||
| output_filename | No |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint and destructiveHint. The description adds behavioral context by naming the Prince engine and the JavaScript execution flag. But it doesn't describe return format or side effects (e.g., whether file is saved to disk), so partial transparency.
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 front-loaded with a clear main sentence and follows with a structured, concise Args list. Each parameter description is useful, though the list is somewhat long.
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?
The description covers parameters well but lacks explanation of the output format or file handling. No output schema exists, so this gap affects completeness. The tool is relatively simple but could state what the returned value is.
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?
With zero schema description coverage, the description's Args section compensates well by providing meaningful descriptions for each parameter, including examples and defaults. It adds value beyond the schema's titles.
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 states 'Convert Markdown content to PDF using Prince' with a specific verb and resource. It clearly differentiates from sibling tools html_to_pdf and url_to_pdf by specifying Markdown as input format.
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 clearly implies usage for Markdown content, providing context. However, it does not explicitly mention alternatives or exclusions, like 'for HTML use html_to_pdf', so it falls short of a 5.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
url_to_pdfARead-onlyInspect
Fetch a URL and convert it to PDF using Prince.
Args:
url: URL of a document to fetch and convert
style: Additional CSS to apply (inline stylesheet content)
page_size: Page size (e.g., A4, letter)
page_margin: Page margins (e.g., 20mm)
javascript: Enable JavaScript execution
pdf_profile: PDF profile (e.g., PDF/A-3b, PDF/UA-1)
output_filename: Output filename for the PDF (default: "output.pdf")
| Name | Required | Description | Default |
|---|---|---|---|
| url | Yes | ||
| style | No | ||
| page_size | No | ||
| javascript | No | ||
| page_margin | No | ||
| pdf_profile | No | ||
| output_filename | No |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds valuable context beyond the annotations by explaining that the tool fetches a URL and uses Prince, plus it gives details about JavaScript execution and PDF profiles. Annotations already declare readOnlyHint and openWorldHint, but the description enriches these with meaningful conversion specifics without contradicting them.
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 concise and well-structured: a one-sentence summary followed by a clean, tabular args list. Every line adds value, with no redundant phrases or extraneous details.
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?
The description covers all parameters but omits the return format (e.g., PDF binary or saved file path) and error behavior, especially since there is no output schema. It also lacks guidance on prerequisites like network access or Prince installation, leaving some gaps for a moderately complex tool.
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?
With 0% schema description coverage, the description carries the full burden of explaining parameters. It provides clear, concise explanations for all seven parameters, including examples for page_size, page_margin, and pdf_profile, making the schema far more understandable.
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 function with a specific verb and resource: 'Fetch a URL and convert it to PDF using Prince.' This distinctly differentiates it from sibling tools html_to_pdf and markdown_to_pdf, which handle HTML and markdown inputs respectively.
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 clearly implies the tool is for URLs, providing clear context on when to use it. However, it does not explicitly mention alternatives or exclusions, such as 'use html_to_pdf for HTML strings,' so it falls short of a 5.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Frequently Asked Questions
Claiming proves that you control a remote MCP connector. It does not move, proxy, or interrupt the server.
Open the connector listing, choose Claim ownership, and sign in to Glama.
Complete one verification method:
GitHub identity — fastest for official registry listings. For a namespace such as
io.github.alice/server, link the matching GitHub user, then choose Claim with GitHub. An organization namespace such asio.github.acme/serveralso needs that organization to have installed the Glama AI GitHub App and approved its permissions, because GitHub discloses organization membership only to apps it has installed. Use HTTP or DNS when it has not.HTTP challenge — works when you can deploy a public file. Generate a token, publish the exact JSON Glama shows at
/.well-known/glama.jsonon the same origin as the connector, then choose Check HTTP challenge.DNS challenge — works when you control DNS but cannot change the server. Generate a token, create the exact TXT record Glama shows, wait for it to propagate, then choose Check DNS challenge.
After verification, Glama sends a confirmation email and gives you access to listing details, thumbnails, health checks, and analytics. Keep the HTTP file or DNS record in place: Glama periodically checks it and ownership remains verified while the token is discoverable.
The HTTP ownership file has this structure:
{
"$schema": "https://glama.ai/mcp/schemas/connector.json",
"claim": "glama_claim_..."
}Claim tokens are opaque, stable, and bound to the signed-in Glama account. They contain no email address or other personal information. If Glama can no longer discover a verified HTTP or DNS token, it starts a seven-day grace period before removing claim-based access. Restore the same token during that period to keep ownership verified. Never publish an email address, Glama session token, GitHub token, or connector credential as ownership proof.
If verification fails, confirm that you copied the current token exactly. The HTTP file must be public, return valid JSON with a successful HTTP response, and stay on the connector's origin. DNS changes may need more time to propagate. A claim cannot transfer to a different origin or hostname: if the connector target changes, Glama starts the grace period and the new target must be claimed separately after the previous claim is released.
For a connector linked to the official MCP Registry, registry updates continue to replace its name, description, and URL by default. After claiming, open Manage connector and enable Use Glama listing details as the source of truth if edits made on Glama should be preserved. Categories and thumbnails are always managed on Glama; registry linkage and technical connection settings continue to sync.

Each tool targets a distinctly different input source: HTML content, Markdown content, and a URL. There is no overlap in purpose, making selection unambiguous.
All tool names follow the exact same verb_noun pattern: html_to_pdf, markdown_to_pdf, url_to_pdf. This is perfectly consistent and predictable.
With only 3 tools, the server is tightly scoped to its core function of PDF conversion from three common input types. Each tool earns its place.
The set covers the most common conversion inputs (HTML, Markdown, URL). A minor gap is lack of direct file input, but these three cover the majority of use cases.
