AI agents call find_task_by_commit to retrieve information from Todos without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries existing data (task associations with commits) without creating, modifying, deleting, or executing operations. It is a straightforward retrieval mechanism analogous to a search or list operation. The use of prefix matching does not change its fundamental read-only nature.
From the tool's definition The tool 'find_task_by_commit' performs a lookup operation to retrieve task information associated with a git commit SHA. The verb 'find' and action of querying/searching for linked data indicates a read-only retrieval operation with no side effects.
Attacks that exploit this kind of access
Find which task a git commit SHA is linked to. Supports prefix matching. It is categorised as a Read tool in the Todos MCP Server, which means it retrieves data without modifying state.
Register the Todos MCP server in PolicyLayer and add a rule for find_task_by_commit: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Todos. Nothing to install.
find_task_by_commit 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 find_task_by_commit rule in your PolicyLayer 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 PolicyLayer policy for find_task_by_commit. 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.
find_task_by_commit is provided by the Todos MCP server (@hasna/todos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
