codewiki_fetch_repo

Fetch generated wiki content for a repository from codewiki.google

Part of the Codewiki MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents call codewiki_fetch_repo to retrieve information from Codewiki 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 codewiki_fetch_repo 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.

Fetch generated wiki content for a repository from codewiki.google. It is categorised as a Read tool in the Codewiki MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on codewiki_fetch_repo? +

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

What risk level is codewiki_fetch_repo? +

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

Can I rate-limit codewiki_fetch_repo? +

Yes. Add a rate_limit block to the codewiki_fetch_repo 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 codewiki_fetch_repo completely? +

Set action: deny in the Intercept policy for codewiki_fetch_repo. 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 codewiki_fetch_repo? +

codewiki_fetch_repo is provided by the Codewiki MCP server (codewiki-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
