Return workspace symbols matching a case-insensitive query.
AI agents call lsp_workspace_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.
The tool performs a search/query operation across workspace symbols, which is a retrieval task with no side effects. It does not execute code, modify files, delete data, or create financial obligations. The LSP (Language Server Protocol) context confirms this is standard code analysis infrastructure for discovering symbol definitions and metadata.
From the tool's definition Tool name and description indicate query-based symbol lookup: 'Return workspace symbols matching a case-insensitive query.' This is a read-only operation that retrieves symbol information without modifying code or executing arbitrary operations.
Attacks that exploit this kind of access
Return workspace symbols matching a case-insensitive query. 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_workspace_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_workspace_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_workspace_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_workspace_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_workspace_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.
