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

@paretools/git Read Risk 3/5

AI agents call bisect to retrieve information from Git 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 bisect 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 bisect tool do? +

Binary search for the commit that introduced a bug. Returns structured data with action taken, current commit, remaining steps estimate, and result.. It is categorised as a Read tool in the Git MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on bisect? +

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

What risk level is bisect? +

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

Can I rate-limit bisect? +

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

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

bisect is provided by the Git MCP server (@paretools/git). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
