Part of the Agda MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call agda_typecheck to retrieve information from Agda 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 agda_typecheck 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.

Type-check an Agda file and return a compact classification-only response. This routes through the same singleton session as agda_load (since issue #39) — it updates the session's loaded file, goal IDs, and mtime, so subsequent tool calls operate on the typechecked file. The only difference from agda_load is the response shape: agda_typecheck omits the full goals-and-warnings text block for a smaller payload. If you want the interactive goals listing, call agda_load instead.. It is categorised as a Read tool in the Agda MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for agda_typecheck. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Agda MCP server.
agda_typecheck is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the agda_typecheck 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.
Set action: deny in the Intercept policy for agda_typecheck. 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.
agda_typecheck is provided by the Agda MCP server (agda-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
