Return tree-sitter symbols converted to LSP DocumentSymbol ranges and kinds.
AI agents call lsp_document_symbols to retrieve information from Syntax Map without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs static code analysis to extract and report symbol information (names, kinds, ranges) from source code. It is a query-based operation that retrieves structural metadata about code without modifying files, executing code, or triggering external operations. The output is informational only, making it a Read-category tool with low blast radius if misused by an AI agent.
From the tool's definition Tool returns tree-sitter symbols converted to LSP DocumentSymbol ranges and kinds. The verb 'Return' and the passive/read-only nature of symbol extraction indicate data retrieval with no mutations or side effects.
Attacks that exploit this kind of access
Return tree-sitter symbols converted to LSP DocumentSymbol ranges and kinds. It is categorised as a Read tool in the Syntax Map MCP Server, which means it retrieves data without modifying state.
Register the Syntax Map MCP server in PolicyLayer and add a rule for lsp_document_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 Syntax Map. Nothing to install.
lsp_document_symbols 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 lsp_document_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.
Set action: deny in the PolicyLayer policy for lsp_document_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.
lsp_document_symbols is provided by the Syntax Map MCP server (kht6163/syntax-map-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
