# Codex LSP Call `lsp` MCP tools through the tool interface; `lsp.*`/`mcp__lsp__*` are tool-call names, not shell commands. ## Tools - `lsp.status`: list configured, installed, missing, disabled, and active language servers. - `lsp.diagnostics`: check one file or directory for LSP diagnostics. Prefer `severity: "error"` after edits. - `lsp.goto_definition`: locate a symbol definition from file, line, and character. - `lsp.find_references`: find usages of a symbol across the workspace. - `lsp.symbols`: inspect document symbols or search workspace symbols. - `lsp.prepare_rename`: check whether a rename is valid at a position. - `lsp.rename`: apply a language-server workspace edit for a rename. ## Config Project config lives at `.codex/lsp-client.json`; user config lives at `~/.codex/lsp-client.json`. ```json { "lsp": { "typescript": { "command": ["typescript-language-server", "--stdio"], "extensions": [".ts", ".tsx", ".js", ".jsx"] } } } ``` Use `lsp.status` first when diagnostics report a missing language server.
