// MCP TOOL REFERENCE

codestral_fim

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

// WHEN AI AGENTS USE THIS TOOL

AI agents invoke codestral_fim to trigger processes or run actions in Mistral. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.

// WHY ENFORCE A POLICY ON CODESTRAL_FIM

codestral_fim can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.

// RECOMMENDED POLICY

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

// FAQ

What does the codestral_fim tool do? +

Fill-in-the-middle code completion with Codestral. Given `prompt` (code preceding the cursor) and `suffix` (code after the cursor), Codestral writes the middle. Use for editor autocomplete scenarios, code-patching agents, or structured refactors where you know the target boundaries. Default stop tokens: [] — let the model decide. Override with `stop` if needed.. It is categorised as a Execute tool in the Mistral MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on codestral_fim? +

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

What risk level is codestral_fim? +

codestral_fim is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit codestral_fim? +

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

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

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