AI agents call get_readme to retrieve information from GitBridge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays existing README.md files from repositories. Reading documentation is a non-destructive operation with no capability to modify data, execute code, or affect system state. The blast radius of misuse is minimal—an AI might retrieve many READMEs or from unauthorized repositories, but cannot alter or delete content. Classified as Read with low severity.
From the tool's definition Tool name 'get_readme' and description 'Get README.md content from a repository' indicate retrieval of static documentation content with no modification or side effects.
Attacks that exploit this kind of access
Get README.md content from a repository. It is categorised as a Read tool in the GitBridge MCP Server, which means it retrieves data without modifying state.
Register the GitBridge MCP server in PolicyLayer and add a rule for get_readme: 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 GitBridge. Nothing to install.
get_readme 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_readme 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_readme. 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_readme is provided by the GitBridge MCP server (saksham-jain177/gitbridge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
