AI agents call find_callees 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 appears to query the FalkorDB-backed code graph to retrieve callees (functions called by a given function), which is a read operation with no side effects. It navigates existing structural relationships in the indexed C# codebase without modifying, executing, or deleting data. The sibling tools context confirms the server's purpose is code analysis and querying, not code modification or execution.
From the tool's definition Tool name 'find_callees' indicates it retrieves or lists functions/methods called by a target symbol. Sibling tools like 'find_dependencies', 'find_usages', 'find_implementations', and 'find_entry_points' all operate as query/retrieval operations over the…
Attacks that exploit this kind of access
find_callees. 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_callees: 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_callees 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_callees 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_callees. 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_callees 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.
find_callees is one line of Synapse's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
