Local code intelligence MCP server and CLI for AI coding agents.
X-ray vision for your agent.
It indexes your repository on disk and serves symbol search, semantic search, call graphs, dependency tracking, document RAG, and impact analysis to Claude Code, Cursor, Windsurf, Codex, Gemini, and any MCP-compatible client — as a persistent MCP server for session-long work, or a one-shot CLI for instant answers when LSP is too slow. Written in Rust. 15 languages. No source code leaves your machine.
Local code intelligence MCP server and CLI for AI coding agents
Codanna's MCP toolset is reachable two ways. Same tools, same surface — pick the mode that fits the workflow.
Persistent MCP server — for session-long agent workflows.
codanna serve # stdio
codanna serve --http # HTTP
codanna serve --https # HTTPS
One-shot CLI — for slash-commands, bash hooks, scripts, CI. No daemon required.
codanna mcp find_symbol name:"my_function"
codanna mcp analyze_impact symbol_name:"my_function"
codanna mcp semantic_search_with_context query:"recursively extract function calls"
codanna mcp semantic_search_with_context is the headline command: it returns N semantic matches, and for each match the symbol identity, signature, docstring, callees, callers, and recursive impact analysis — five MCP tools fused into one query.
The one-shot CLI is also what makes codanna skill-friendly: an Agent Skill can wrap codanna mcp commands directly in Claude Code, Cursor, Windsurf, Codex, Gemini, or any harness that runs shell commands — no MCP plumbing required.
The headline command, run against codanna's own source tree. One call, and the agent has the symbol, its documentation, signature, callees with exact call sites, callers, and blast radius:
$ codanna mcp semantic_search_with_context query:"recursively extract function calls" limit:1

Guidance: Found one match with full context. Review the relationships to understand how this fits into the codebase.
Every result carries file:line coordinates the agent can open directly, symbol_ids it can reuse to disambiguate name collisions, and a guidance hint it can chain on. Add --json for the structured envelope.
Codanna runs on your machine. The repository index lives on disk under .codanna/. The embedding model downloads once on first use, then runs locally. No source code, symbols, or queries are sent to a remote API by default. Remote OpenAI-compatible embeddings are opt-in: remote_url under [semantic_search] in settings.toml, or CODANNA_EMBED_* environment variables; the API key is environment-only.

Your AI assistant gains structured knowledge of your code:
The difference: Codanna understands code structure. It knows parseConfig is a function that calls validateSchema, not just a string match.
Performance: parser throughput 76,000-249,000 symbols/second depending on language; warm-server lookups under 10 ms (0.3 ms exact, ~3 ms semantic). Parsing is the fast layer; embedding generation during indexing takes longer and scales with your cores. Measured numbers, machine spec, and reproduction commands: Benchmarks.
Languages: Rust, Python, JavaScript, TypeScript, Java, Kotlin, Go, PHP, C, C++, C#, Clojure, Lua, Swift, GDScript.
Two skills over the index, driven by the agent: it picks the view that fits the question. x-ray covers scoped questions — a symbol's blast radius as a call DAG, module structure as a collapsible tree or radial poster, cross-module calls as an edge-bundle page. graph covers codebase shape: the module disc with hubs at the centre, a commit timeline, and a heatmap. Symbol search, detail panels with highlighted signatures, call-graph navigation. The disc renderer is adapted from vault-graph by Lukas Proprentner (MIT).
/plugin marketplace add bartolli/codanna
/plugin install codanna-toolset@codanna
Add codanna to any MCP-compatible client. Project-scoped .mcp.json (Claude Code, Cursor, Windsurf):
{
"mcpServers": {
"codanna": {
"command": "codanna",
"args": ["--config", ".codanna/settings.toml", "serve", "--watch"]
}
}
}
--watch keeps the index hot as files change. Transports: stdio, HTTP, HTTPS. See Integration Guides for Claude Desktop, Gemini, Codex, and network setups.
