WHAT IT DOES

What get_related_symbols does on Trace

AI agents call get_related_symbols to retrieve information from Trace without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why get_related_symbols is rated Low

This tool retrieves and queries code structure information (related symbols, their locations, and relationships) to aid code navigation and understanding. It has no side effects, creates no state changes, and performs no operations. The explicit 'Read-only' designation and the return of informational JSON confirm this is a read operation with minimal blast radius if misused by an agent.

From the tool's definition Tool description explicitly states 'Read-only' and 'Find symbols related via co-location... Use when exploring a symbol to discover sibling code.' The function returns JSON data about related symbols without modifying, executing, or deleting anything.

RECOMMENDED RULE

The rule that runs get_related_symbols safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Trace, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_related_symbols, this is the rule to start with:

get_related_symbols Allowed

get_related_symbols is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_related_symbols": {}
  }

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Trace, apply this rule, and every get_related_symbols call is checked against it from then on.

FAQ

Questions about get_related_symbols

What does the get_related_symbols tool do? +

Find symbols related via co-location (same file), shared importers, and name similarity. Use when exploring a symbol to discover sibling code. For call-graph relationships use get_call_graph instead; for all usages use find_usages. Read-only. Returns JSON: { related: [{ symbol_id, name, kind, file, relation_type, score }] }. It is categorised as a Read tool in the Trace MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get_related_symbols? +

Register the Trace MCP server in PolicyLayer and add a rule for get_related_symbols: 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 Trace. Nothing to install.

What risk level is get_related_symbols? +

get_related_symbols is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit get_related_symbols? +

Yes. Add a rate_limit block to the get_related_symbols 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.

How do I block get_related_symbols completely? +

Set action: deny in the PolicyLayer policy for get_related_symbols. 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.

What MCP server provides get_related_symbols? +

get_related_symbols is provided by the Trace MCP server (nikolai-vysotskyi/trace-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
