Get SRC server identity, version, and description. Use to verify the MCP server is running correctly.

Index a codebase for semantic code search. USE THIS FIRST before search_code. Required once per project - creates vector embeddings for 55 configured language modes across 99 extensions. After initial indexing, use update_index for incremental updates.

Search code semantically using natural language queries, hybrid vector/BM25 retrieval, and deterministic identifier reranking. USE THIS to find code by concept/meaning (e.g., 'authentication logic', 'error handling'). Requires index_codebase first. Returns relevant code chunks with file locations, function names, and call relationships (who calls what).

Check if a codebase is indexed and ready for search. USE THIS to verify index exists before searching. Returns file count, chunk count, and indexed languages.

Refresh the search index after code changes. USE THIS instead of re-indexing - it's fast because it only processes changed files (SHA-256 hash detection). Use dryRun=true to preview changes first.

Parse code and return the Abstract Syntax Tree (AST). Supports multiple languages including JavaScript, TypeScript, Python, Go, Rust, Java, C, C++, and more.

Execute Tree-sitter SCM queries on code to find patterns. Use preset queries (functions, classes, imports, exports, comments, strings, variables, types) or custom SCM query patterns.

Extract all code symbols (functions, classes, variables, etc.) from a file. Returns structured information including name, type, location, and signature for each symbol.

Perform a comprehensive analysis of a source code file. Returns symbols, imports, exports, and code metrics. Optionally includes the full AST.

Analyze function call relationships in a codebase. Query callers/callees for a specific function or get full call graph statistics.

Read-only code navigation across a project: find symbol definitions, textual references, imports, and exports with precise byte offsets and bounded snippets.

Read-only project architecture analysis: resolve imports/exports, expose a dependency graph, detect cycles, and rank inbound/outbound hotspots.

Read-only bounded source retrieval by exact UTF-8 byte offsets, with line/column positions and no code execution.

Read-only blast-radius analysis for changed files using the project dependency graph and reverse transitive closure.

Inspect embedding provider health, index compatibility, path-security configuration, and resource limits without modifying the project.

Read bounded local metrics, runtime counters, and secret-free audit status as structured JSON or a Prometheus text export; no telemetry leaves the process.

List the safe project roots available to SRC and each index status. Use this before querying multiple configured repositories; projects remain independently indexed and queried.

Build a bounded, task-focusable repository map of important files and symbols. Ranking uses import-graph centrality plus optional path/symbol focus, so an agent can orient itself before reading source.

Resolve the smallest Tree-sitter symbol containing an exact 1-based line and 0-based column. Returns byte-precise ranges and a bounded source body for efficient code navigation.

Prepare a bounded one-call agent dossier combining project profile, revision-aware memory, relevant artifacts, local Git changes, a PageRank-style repository map, and indexed code search. Each layer degrades independently and receives a fair share of the token budget.

Conservatively identify unexported functions, methods, classes, and types with no visible references. Read-only heuristic analysis with confidence and limitations; never removes code.

Read-only Git working-tree analysis that maps changed files and zero-context diff hunks to current source symbols. Includes untracked files, bounded output, and explicit limitations when symbols cannot be resolved.

Discover and search bounded project documentation such as README files, architecture notes, ADRs, specifications, plans, runbooks, security notes, and changelogs without executing or persisting their content.

Build a bounded local onboarding profile: project type, languages, frameworks, manifests, scripts, workspaces, entrypoints, tests, configuration, documentation, and path aliases. It never executes project commands.

Navigate local code with an imported SCIP catalog or allow-listed local language server when available, using definitions, references, implementations, hover, type hierarchies, and diagnostics; otherwise fall back explicitly to bounded Tree-sitter analysis with confidence and coverage metadata.

Build a bounded local symbol-level graph combining modules, definitions, imports, references, calls, inheritance, tests, routes, events, and dependency-injection signals, with trace paths and blast-radius analysis.

Read bounded, project-isolated local memory containing decisions, constraints, facts, todos, and notes. It never calls a remote service and marks all stored content as untrusted data.

Create, update, or delete one bounded record in the isolated local project memory. Writes are atomic, optimistic-concurrency aware, secret-redacted by default, and never execute project content.

Read the bounded, project-isolated local artifact catalog created by refresh_project_catalog, optionally including redacted live document excerpts.

Scan local project documentation and persist a bounded metadata-only artifact catalog with typed references. It never stores document bodies, contacts remote services, or executes project content.

Inspect bounded local Git status, diff, history, optional churn hotspots, local revision comparisons, blame, CODEOWNERS, and changed-symbol analysis. It uses only fixed non-remote Git commands, rejects arbitrary command arguments, and never executes project scripts.

Create, verify, restore, list, and clean bounded local snapshots of the semantic index. Snapshots never leave the project, restore uses verified files and a recovery snapshot by default, and no project code is executed.

Optionally run an installed local ast-grep, Semgrep, or CodeQL analyzer with fixed non-shell arguments, strict path bounds, timeouts, output caps, and redaction. Disabled by default; no project scripts or remote rules are executed.

Import a local SCIP JSON export, or ask an installed local scip CLI to print a binary SCIP index as JSON, into the project-isolated catalog used by semantic navigation. No remote service or project script is executed.

Inspect, compact, and migrate the local LanceDB index with bounded, explicit maintenance operations; no project code is executed.
