使用 Docker
如果您希望在 Docker 容器中运行 MCP 服务器:
构建 Docker 镜像:
首先,在项目根目录(或您喜欢的任何位置)创建一个
Dockerfile:FROM node:18-alpine WORKDIR /app # Install the latest version globally RUN npm install -g @upstash/context7-mcp # Expose default port if needed (optional, depends on MCP client interaction) # EXPOSE 3000 # Default command to run the server CMD ["context7-mcp"]然后,使用标签(例如
context7-mcp)构建镜像。**确保 Docker Desktop(或 Docker 守护进程)正在运行。**在保存Dockerfile目录中运行以下命令:docker build -t context7-mcp .配置您的 MCP 客户端:
更新您的 MCP 客户端的配置以使用 Docker 命令。
cline_mcp_settings.json 的示例:
{ "mcpServers": { "Сontext7": { "autoApprove": [], "disabled": false, "timeout": 60, "command": "docker", "args": ["run", "-i", "--rm", "context7-mcp"], "transportType": "stdio" } } }注意:这是一个示例配置。请参考本 README 中针对您的 MCP 客户端(例如 Cursor、VS Code 等)的具体示例来调整结构(例如,
mcpServersvsservers)。另外,请确保args中的镜像名称与docker build命令中使用的标签匹配。
在 Windows 中安装
Windows 上的配置与 Linux 或 macOS 上略有不同(示例中使用了Cline )。其他编辑器的配置原理相同,请参考command和args的配置。
{
"mcpServers": {
"github.com/upstash/context7-mcp": {
"command": "cmd",
"args": [
"/c",
"npx",
"-y",
"@upstash/context7-mcp"
],
"disabled": false,
"autoApprove": []
}
}
}环境变量
DEFAULT_MINIMUM_TOKENS:设置文档检索的最小令牌数(默认值:10000)。
例子:
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["-y", "@upstash/context7-mcp"],
"env": {
"DEFAULT_MINIMUM_TOKENS": "10000"
}
}
}
}可用工具
resolve-library-id:将通用库名称解析为与 Context7 兼容的库 ID。libraryName(必填)
get-library-docs:使用与 Context7 兼容的库 ID 获取库的文档。context7CompatibleLibraryID(必需)topic(可选):将文档集中在特定主题上(例如,“路由”,“钩子”)tokens(可选,默认 10000):返回的最大 token 数量。如果值小于配置的DEFAULT_MINIMUM_TOKENS值或默认值 10000,则会自动增加到该值。
发展
克隆项目并安装依赖项:
bun i建造:
bun run build本地配置示例
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["tsx", "/path/to/folder/context7-mcp/src/index.ts"]
}
}
}使用 MCP Inspector 进行测试
npx -y @modelcontextprotocol/inspector npx @upstash/context7-mcp故障排除
未找到模块
如果您看到此错误,请尝试使用bunx而不是npx 。
{
"mcpServers": {
"context7": {
"command": "bunx",
"args": ["-y", "@upstash/context7-mcp"]
}
}
}这通常可以解决模块解析问题,特别是在npx无法正确安装或解析包的环境中。
ESM 解析问题
如果遇到类似错误: Error: Cannot find module 'uriTemplate.js'请尝试使用--experimental-vm-modules标志运行:
{
"mcpServers": {
"context7": {
"command": "npx",
"args": [
"-y",
"--node-options=--experimental-vm-modules",
"@upstash/context7-mcp"
]
}
}
}TLS/证书问题
使用带有npx的--experimental-fetch标志来绕过与 TLS 相关的问题:
{
"mcpServers": {
"context7": {
"command": "npx",
"args": [
"-y",
"--node-options=--experimental-fetch",
"@upstash/context7-mcp"
]
}
}
}MCP 客户端错误
尝试将
@latest添加到包名称中。尝试使用
bunx作为替代方案。尝试使用
deno作为替代方案。确保您使用的是 Node v18 或更高版本以获得
npx的本机获取支持。

Available Tools
2 toolsquery-docsQuery DocumentationARead-onlyInspect
Retrieves and queries up-to-date documentation and code examples from Context7 for any programming library or framework.
You must call 'resolve-library-id' first to obtain the exact Context7-compatible library ID required to use this tool, UNLESS the user explicitly provides a library ID in the format '/org/project' or '/org/project/version' in their query.
IMPORTANT: Do not call this tool more than 3 times per question. If you cannot find what you need after 3 calls, use the best information you have.
| Name | Required | Description | Default |
|---|---|---|---|
| query | Yes | The question or task you need help with. Be specific and include relevant details. Good: 'How to set up authentication with JWT in Express.js' or 'React useEffect cleanup function examples'. Bad: 'auth' or 'hooks'. IMPORTANT: Do not include any sensitive or confidential information such as API keys, passwords, credentials, or personal data in your query. | |
| libraryId | Yes | Exact Context7-compatible library ID (e.g., '/mongodb/docs', '/vercel/next.js', '/supabase/supabase', '/vercel/next.js/v14.3.0-canary.87') retrieved from 'resolve-library-id' or directly from user query in the format '/org/project' or '/org/project/version'. |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Adds behavioral context beyond the readOnlyHint annotation: the 3-call limit, prerequisite step, and warning against sensitive data. No contradiction with annotations.
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?
Three short paragraphs each serving a distinct purpose: purpose, prerequisite, limitation. Front-loaded with the core action, no redundant information.
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?
Covers prerequisite, usage limit, and parameter guidance. Lacks explicit description of output format, but since the tool retrieves documentation and code examples, the output type is reasonably inferable.
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 provides 100% coverage with detailed descriptions for both parameters. The tool description reinforces the relationship between libraryId and resolve-library-id but adds little semantic meaning beyond what's already in the schema.
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 it retrieves and queries documentation and code examples from Context7 for any library, distinguishing it from the sibling 'resolve-library-id' tool which is for obtaining library IDs.
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?
Explicitly instructs to use 'resolve-library-id' first unless user provides library ID, and imposes a 3-call limit per question, providing clear guidance on when and how many times to use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
resolve-library-idResolve Context7 Library IDARead-onlyInspect
Resolves a package/product name to a Context7-compatible library ID and returns matching libraries.
You MUST call this function before 'query-docs' to obtain a valid Context7-compatible library ID UNLESS the user explicitly provides a library ID in the format '/org/project' or '/org/project/version' in their query.
Selection Process:
Analyze the query to understand what library/package the user is looking for
Return the most relevant match based on:
Name similarity to the query (exact matches prioritized)
Description relevance to the query's intent
Documentation coverage (prioritize libraries with higher Code Snippet counts)
Source reputation (consider libraries with High or Medium reputation more authoritative)
Benchmark Score: Quality indicator (100 is the highest score)
Response Format:
Return the selected library ID in a clearly marked section
Provide a brief explanation for why this library was chosen
If multiple good matches exist, acknowledge this but proceed with the most relevant one
If no good matches exist, clearly state this and suggest query refinements
For ambiguous queries, request clarification before proceeding with a best-guess match.
IMPORTANT: Do not call this tool more than 3 times per question. If you cannot find what you need after 3 calls, use the best result you have.
| Name | Required | Description | Default |
|---|---|---|---|
| query | Yes | The user's original question or task. This is used to rank library results by relevance to what the user is trying to accomplish. IMPORTANT: Do not include any sensitive or confidential information such as API keys, passwords, credentials, or personal data in your query. | |
| libraryName | Yes | Library name to search for and retrieve a Context7-compatible library ID. |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate readOnlyHint=true, which is consistent with the tool's purpose. The description adds important behavioral details beyond annotations, such as a 3-call limit per question, handling of ambiguous queries, and a warning not to include sensitive information in the 'query' parameter.
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 well-structured with clear sections, but it is somewhat lengthy. It front-loads the essential purpose and usage note, but the selection process details could be more succinct. Still, it remains clear and organized.
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 there is no output schema, the description adequately explains the response format. It covers edge cases like multiple matches, no matches, and ambiguous queries, providing complete guidance for the agent to handle various scenarios.
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 coverage is 100%, so the baseline is 3. The description adds value by explaining the role of each parameter: 'libraryName' is the name to search for, and 'query' is the user's original question used for ranking. It also includes a critical warning about sensitive data in 'query', which enhances understanding.
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?
Clearly states that the tool resolves a package/product name to a Context7-compatible library ID. It distinguishes itself from the sibling tool 'query-docs' by noting it must be called first, and includes specific details about selection criteria and response 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?
Explicitly specifies when to call this tool: before 'query-docs' unless the user provides a library ID in a specific format. It also provides a detailed selection process and response format, guiding the agent on how to use the tool correctly.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

resolve-library-id
TDQS
Each tool has a distinct and complementary purpose: one resolves library names to IDs, the other queries documentation using that ID. There is no overlap.
Both tools follow the same verb_noun pattern with snake_case: 'resolve-library-id' and 'query-docs'. Consistent and predictable.
With only two tools, the surface is minimal but still covers the core workflow for querying documentation. It is slightly thin but appropriate for a focused server.
The two tools form a complete workflow: resolve then query. No obvious gaps for the stated purpose, though additional tools like list_libraries could enhance completeness.
