AI agents call search_synapse to retrieve information from Synapse without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs keyword-based searches to retrieve and discover Synapse entities (Datasets, Projects, Folders, Files, Tables, etc.). It has no side effects—it only queries and returns results. It does not create, modify, delete, execute code, or commit financial transactions.
From the tool's definition Tool name is 'search_synapse' and description states it 'Search[es] Synapse entities using keyword queries.' Search operations are non-destructive queries that retrieve data without modification.
Attacks that exploit this kind of access
Search Synapse entities using keyword queries. It is categorised as a Read tool in the Synapse MCP Server, which means it retrieves data without modifying state.
Register the Synapse MCP server in PolicyLayer and add a rule for search_synapse: 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 Synapse. Nothing to install.
search_synapse 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_synapse 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_synapse. 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_synapse is provided by the Synapse MCP server (sage-bionetworks/synapse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
