Searches and filters repositories by technology stack, programming language, topics, or minimum stars.
AI agents call search_projects_by_tech to retrieve information from GitInsight-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a data retrieval tool that queries GitHub profile/repository data without creating, modifying, deleting, or executing any operations. The action is passive search/filter functionality with zero side effects. Severity is low because even if misused by an AI agent, it can only read existing public data without causing harm or blast radius.
From the tool's definition Tool performs 'searches and filters repositories' with no modification capabilities - it only retrieves publicly available GitHub repository metadata based on filter criteria (technology stack, language, topics, stars).
Attacks that exploit this kind of access
Searches and filters repositories by technology stack, programming language, topics, or minimum stars. It is categorised as a Read tool in the GitInsight-MCP MCP Server, which means it retrieves data without modifying state.
Register the GitInsight- MCP server in PolicyLayer and add a rule for search_projects_by_tech: 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 GitInsight-MCP. Nothing to install.
search_projects_by_tech 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_projects_by_tech 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_projects_by_tech. 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_projects_by_tech is provided by the GitInsight- MCP server (marwaniiwael18/gitinsight-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
