Get repository ID for mutations
AI agents call get_repo_id to retrieve information from GitHub Project MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata (a repository ID) needed for subsequent operations. It performs no side effects, creates no data, executes no code, and deletes nothing. It is purely informational, supporting other tools by providing necessary identifiers. The phrase 'for mutations' indicates it is a dependency for other operations, but the tool itself is a simple getter.
From the tool's definition Tool name 'get_repo_id' and description 'Get repository ID for mutations' indicate a query operation that retrieves an identifier.
Attacks that exploit this kind of access
Get repository ID for mutations. It is categorised as a Read tool in the GitHub Project MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GitHub Project MCP Server MCP server in PolicyLayer and add a rule for get_repo_id: 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 GitHub Project MCP Server. Nothing to install.
get_repo_id 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 get_repo_id 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 get_repo_id. 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.
get_repo_id is provided by the GitHub Project MCP Server MCP server (jaqarx/github-project-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
