AI agents call find_implementations 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 retrieves structural information about code (specifically, implementations of interfaces or abstract classes) from the indexed codebase. It has no side effects—it reads the graph database without creating, modifying, or deleting data. The tool belongs in the 'Read' category alongside similar query tools on the server.
From the tool's definition Tool name 'find_implementations' is a query operation similar to sibling tools like 'find_callees', 'find_usages', and 'find_dependencies'. The naming pattern indicates information retrieval without modification.
Attacks that exploit this kind of access
find_implementations. 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 find_implementations: 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.
find_implementations 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 find_implementations 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 find_implementations. 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.
find_implementations is provided by the Synapse MCP server (synappscodecomprehension/synapps). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
