search_repositories
AI agents call search_repositories to retrieve information from Repo Radar MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves data about repositories without side effects. It performs discovery and filtering operations as described in the server's capabilities. No data is modified, deleted, or executed. The risk is minimal as misuse would only return repository information to an AI agent, which cannot cause harm beyond potentially wasting API calls or accessing public GitHub data.
From the tool's definition Tool name 'search_repositories' combined with server description stating it 'Enables searching, filtering, ranking, and evaluating open-source repositories'.
Attacks that exploit this kind of access
search_repositories. It is categorised as a Read tool in the Repo Radar MCP MCP Server, which means it retrieves data without modifying state.
Register the Repo Radar MCP server in PolicyLayer and add a rule for search_repositories: 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 Repo Radar MCP. Nothing to install.
search_repositories 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 search_repositories 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 search_repositories. 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.
search_repositories is provided by the Repo Radar MCP server (javiermorron/repo-radar-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
