Description from the maker (original English)
Local-first SCIP code navigation and Zoekt search over your own indexed repositories
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.

Your coding agent should not spend its context window on grep.
When your agent asks *"where is AuthService used?"*, grep returns comments, markdown, test fixtures, and similarly named symbols in one noisy pile. The agent burns context re-reading files to filter signal from noise — and still misses call sites.
jarvis precomputes a local code-intelligence layer so your agent calls findReferences for exact occurrences, goToDefinition for the defining range, callHierarchy for call paths, and searchCode for precise lexical search — ten MCP tools for Claude Code, Cursor, or any MCP client. Your code and indexes never leave your machine.
| Without jarvis | Grep → comments, tests, imports mixed with real hits → opens files to filter → guesses at call sites → burns context on search instead of reasoning |
| With jarvis | findReferences("AuthService") → exact file-and-range occurrences → callHierarchy for the graph → searchCode("token refresh") → answers without opening every match |
Quick start · MCP tools · Dashboard · Limits · Details · Docs
1. Install the standalone binary:
brew install jarvis-intelligence/jarvis/jarvis
Linux users need Homebrew/Linuxbrew installed first. The formula supports macOS arm64/x86_64 and Linux arm64/x86_64, installs both jarvis and jarvis-server, and embeds Python 3.12, dashboard assets, tree-sitter libraries, watch, scip, zoekt-git-index, and zoekt-webserver. Homebrew supplies universal-ctags. No Python, uv, pip, or PyPI installation is required.
Upgrade with brew upgrade jarvis; recover a damaged installation with brew reinstall jarvis.
2. Index a repo (slug defaults to the directory name):
jarvis index /path/to/your/repo
3. Register the MCP server:
claude mcp add jarvis --scope user -- jarvis-server
Ask your agent *"find all references to AuthService"* — it calls findReferences instead of grepping.
Other MCP clients (Cursor, Claude Desktop, any stdio client)
{
"mcpServers": { "jarvis": { "command": "jarvis-server" } } }
If your client can't find jarvis-server on PATH (GUI apps often don't inherit your shell's), use the absolute path from which jarvis-server.
Claude Code plugin (registers MCP + ships agent skills)
Install the Homebrew binary first. The plugin adds jarvis skills and can register the already-installed jarvis-server.
/plugin marketplace add jarvis-intelligence/jarvis-index
/plugin install jarvis@jarvis

Optional language indexers
The standalone package includes the SCIP converter and both Zoekt binaries. The Homebrew formula does not install setup.sh; from a jarvis source checkout, install the optional per-language indexer for your repo:
| Language | Installer | Toolchain |
|---|---|---|
| TypeScript/TSX | sh setup.sh --only scip-typescript | Node.js/npm |
| Python | sh setup.sh --only scip-python | Node.js/npm |
| Java/Kotlin | sh setup.sh --only scip-java | JDK; Kotlin repos require Kotlin 2.2.0 exactly |
| Swift | sh setup.sh --only scip-swift | Xcode on macOS arm64 |
For Maven-built Java repositories on macOS, also install a modern Bash with brew install bash, then run sh setup.sh --only bash-shim from that same source checkout. Reindex after adding an indexer. Without the matching indexer, documentSymbols and goToDefinition still work via Tree-sitter where coverage exists; findReferences, callHierarchy, and typeHierarchy return recovery guidance.
Not included
semanticSearch is registered for MCP compatibility but is excluded from the standalone distribution. It returns a Homebrew-specific unavailability error that points to the source-build steps below; lexical search and symbol search remain available.
Source-build semantic search
The standalone Homebrew package excludes semantic dependencies. In a source checkout, install them with:
uv run jarvis install-semantic
Then index explicitly:
uv run jarvis index /path/to/repo --semantic
install-semantic also pre-downloads the embedding model (BAAI/bge-m3, ~4.3 GB, one time) into the shared Hugging Face cache (~/.cache/huggingface/); every indexed repo reuses it. If the download is interrupted, the next jarvis index retries it automatically.
| Tool | What it does |
|---|---|
goToDefinition | Resolve a symbol to its defining file and range |
findReferences | Every occurrence of a symbol across the indexed repo |
callHierarchy | Incoming/outgoing calls for a symbol |
typeHierarchy | Supertypes/subtypes |
documentSymbols | Outline of every symbol defined in one file |
searchCode | Zoekt lexical/regex search, optionally filtered to one repo |
semanticSearch | Returns the Homebrew distribution's semantic-unavailability error |
blastRadius | Which other indexed repos depend on a package, up to 2 hops |
getIndexStatus | Published commit, freshness, staleness vs. working tree |
indexRepo | Build an index for a git repo at path |

One indexing CLI writes precomputed indexes into ~/.jarvis; one stdio runtime reads them down. The two share no other contract.

Known upstream limitations
scip-kotlinc is compiled against one pinned release (currently 2.2.0). Detected automatically.brew install bash fixes it.jarvis index refuses an older scip rather than publishing a broken index.Configuration
| Variable | Purpose |
|---|---|
JARVIS_DATA_DIR | Override default ~/.jarvis for all indexes and registry |
The source-development semantic path has additional model-prefix overrides; they have no effect in the standalone distribution.
