List pull requests for a repository: number, title, state, author, draft flag, merged status + time, head/base branch, and created time. Filter by state (open/closed/all); paginate. Read-only; no caller key needed.
AI agents call github.pulls to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries pull request metadata from a GitHub repository with no side effects, no data modification, and no execution capabilities. It is a straightforward read operation that lists existing data. Low severity because pull request metadata is typically public information with minimal sensitive content, and misuse cannot alter or delete data.
From the tool's definition Tool description explicitly states 'List pull requests for a repository' with specific read-only data fields (number, title, state, author, draft flag, merged status, branch, created time). Description emphasizes 'Read-only; no caller key needed'.
Attacks that exploit this kind of access
List pull requests for a repository: number, title, state, author, draft flag, merged status + time, head/base branch, and created time. Filter by state (open/closed/all); paginate. Read-only; no caller key needed. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the MCP server in PolicyLayer and add a rule for github.pulls: 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 Mcp. Nothing to install.
github.pulls 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 github.pulls 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 github.pulls. 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.
github.pulls is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
