Search GitHub for code, repositories, or users. Use when you need to find code examples, open source projects, or developers. Supports advanced syntax: filename:, path:, repo:, user:, language:, in:file.
AI agents call github_search to retrieve information from Mcp Omnisearch without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves publicly available GitHub data through search queries. It has no capability to create, modify, delete, execute code, or perform financial transactions. The worst-case misuse would be discovering sensitive information in public repositories, which is within the low-severity read-access threat model since the data is already public on GitHub.
From the tool's definition Tool description explicitly states 'Search GitHub for code, repositories, or users' and supports search queries with filters (filename:, path:, repo:, user:, language:, in:file).
Attacks that exploit this kind of access
Search GitHub for code, repositories, or users. Use when you need to find code examples, open source projects, or developers. Supports advanced syntax: filename:, path:, repo:, user:, language:, in:file. It is categorised as a Read tool in the Mcp Omnisearch MCP Server, which means it retrieves data without modifying state.
Register the Mcp Omnisearch MCP server in PolicyLayer and add a rule for github_search: 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 Omnisearch. Nothing to install.
github_search 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_search 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_search. 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_search is provided by the Mcp Omnisearch MCP server (mcp-omnisearch). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
