What find_symbol does on Breakpoint
AI agents call find_symbol to retrieve information from Breakpoint without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
name | string | Yes | Symbol name to look for |
exact | boolean | — | Require an exact name match (default false = substring) |
kinds | array | — | Restrict to these declaration kinds (default: all) |
max_results | integer | — | Cap on returned declarations (default 200) |
Parameters from the server's own tool schema.
Why find_symbol is rated Low
Even though find_symbol only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs find_symbol safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Breakpoint, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For find_symbol, this is the rule to start with:
find_symbol 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 Breakpoint, apply this rule, and every find_symbol call is checked against it from then on.
Questions about find_symbol
Locate where GDScript symbols are DECLARED across the project — class_name, inner class, func, signal, enum, const and var. Read-only project index. This is the workspace-symbol answer Godot's language server does not implement (gd_workspace_symbols returns 'unsupported'); for the semantic, position-based lookup on a single build use gd_definition instead. It is categorised as a Read tool in the Breakpoint MCP Server, which means it retrieves data without modifying state.
find_symbol accepts 4 parameters: name, exact, kinds, max_results. Required: name. The full parameter table on this page comes from the server's own tool schema.
Register the Breakpoint MCP server in PolicyLayer and add a rule for find_symbol: 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 Breakpoint. Nothing to install.
find_symbol 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_symbol 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_symbol. 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_symbol is provided by the Breakpoint MCP server (breakpoint-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
