@upstash/context7-mcp Read Risk 2/5

AI agents call query-docs to retrieve information from Context7 without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though query-docs only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

What does the query-docs tool do? +

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.. It is categorised as a Read tool in the Context7 MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on query-docs? +

Add a rule in your Intercept YAML policy under the tools section for query-docs. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Context7 MCP server.

What risk level is query-docs? +

query-docs is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit query-docs? +

Yes. Add a rate_limit block to the query-docs rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block query-docs completely? +

Set action: deny in the Intercept policy for query-docs. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides query-docs? +

query-docs is provided by the Context7 MCP server (@upstash/context7-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
