What hybrid_bm25_vector_search does on Mcpg
AI agents call hybrid_bm25_vector_search to retrieve information from Mcpg without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why hybrid_bm25_vector_search is rated Low
Hybrid search tools typically retrieve and rank data based on multiple relevance signals without altering the underlying database. Despite the empty description reducing certainty slightly, the naming convention and sibling tools (which are analysis/configuration utilities) strongly indicate this is a Read operation.
From the tool's definition Tool name 'hybrid_bm25_vector_search' indicates a search operation combining BM25 (full-text search) and vector similarity. The name structure and context among sibling analysis tools suggest this performs querying/retrieval without modification.
Attacks that exploit this kind of access
The rule that runs hybrid_bm25_vector_search safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mcpg, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For hybrid_bm25_vector_search, this is the rule to start with:
hybrid_bm25_vector_search is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Mcpg, apply this rule, and every hybrid_bm25_vector_search call is checked against it from then on.
