Overview

AI-generated overview

Local-first code intelligence that lets an assistant navigate indexed repositories with exact symbol references, definitions, call hierarchies and lexical code

What you can do
jarvis precomputes a local code-intelligence layer over your own indexed repositories so an assistant can query symbols instead of grepping. It exposes ten MCP tools, including findReferences for exact occurrences, goToDefinition for defining ranges, callHierarchy and typeHierarchy for relationships, documentSymbols for file outlines, searchCode for Zoekt lexical or regex search, blastRadius for cross-repo package dependents, getIndexStatus for freshness, and indexRepo to build an index (R4, R46-R56). Indexing is explicit and the query path is read-only (R64, R70).
When to use it
Use it when a coding agent repeatedly greps a repository and burns context filtering comments, tests and similarly named symbols from real hits (R1-R3, R6). It suits questions such as where a symbol is used, where it is defined, or what calls it, answered from precomputed indexes rather than by opening every match (R7, R18). It is retrieval only, so renames and refactors are out of scope (R63).
Requirements
macOS arm64/x86_64 or Linux arm64/x86_64 only; Windows is not supported (R60). Install the standalone Homebrew binary, which embeds Python 3.12 and the needed tooling, so no Python, uv, pip or PyPI install is required (R12, R14); Linux needs Homebrew/Linuxbrew first (R11). Register the local stdio server, for example jarvis-server, and use its absolute path if the client cannot find it on PATH (R17, R19, R20). Optional per-language indexers need Node.js/npm, a JDK, Xcode or a modern Bash (R28-R-
Before you install
Indexing is explicit: run jarvis index or jarvis watch before querying (R64). The runtime path never writes and queries open the published snapshot read-only (R70), and jarvis never edits code (R63). Indexes are stored locally under ~/.jarvis, overridable with JARVIS_DATA_DIR (R84), and the README states code and indexes never leave the machine (R5). Optional semantic search downloads a roughly 4.3 GB embedding model into the shared Hugging Face cache (R42).

Installation

In SourceWeft

  1. Open Codeintel in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

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 jarvisGrep → comments, tests, imports mixed with real hits → opens files to filter → guesses at call sites → burns context on search instead of reasoning
With jarvisfindReferences("AuthService") → exact file-and-range occurrences → callHierarchy for the graph → searchCode("token refresh") → answers without opening every match

[grep returns noisy results vs jarvis findReferences returning 10 exact file:line:col occurrences]

Quick start

1. Install the standalone binary:

bash
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):

bash
jarvis index /path/to/your/repo

3. Register the MCP server:

bash
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)
json
{  "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:

LanguageInstallerToolchain
TypeScript/TSXsh setup.sh --only scip-typescriptNode.js/npm
Pythonsh setup.sh --only scip-pythonNode.js/npm
Java/Kotlinsh setup.sh --only scip-javaJDK; Kotlin repos require Kotlin 2.2.0 exactly
Swiftsh setup.sh --only scip-swiftXcode 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:

bash
uv run jarvis install-semantic

Then index explicitly:

bash
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.

Requirements and limits

  • macOS arm64/x86_64 and Linux arm64/x86_64 only. Windows is not supported.
  • Semantic search is unavailable in the Homebrew distribution.
  • One language per repo — detected by extension plurality across git-tracked files; override with --language.
  • jarvis never edits code. It is the retrieval half — Serena complements it for renames/refactors.
  • Indexing is explicit — run jarvis index (or jarvis watch) before querying.

Details

How it works

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

[jarvis architecture]

  • Publishing is atomic — a reindex writes a new snapshot, then flips the current pointer via os.replace. A query reading the old snapshot keeps working; no downtime window.
  • The runtime path never writes — every query opens the published snapshot read-only (mode=ro&immutable=1).
  • The package graph is rebuilt, not accumulated — each reindex clears that repo's outgoing edges before recomputing.

Known upstream limitations
  • scip-java can't index Android/Gradle repos — its Gradle plugin keys off standard source sets that AGP replaces (scip-java#177). Detected automatically; degrades to search-only.
  • Kotlin indexing requires an exact Kotlin version match — scip-kotlinc is compiled against one pinned release (currently 2.2.0). Detected automatically.
  • Maven-built Java repos need bash ≥ 4.4 on macOS — brew install bash fixes it.
  • Swift indexing requires scip >= v0.9.0 — older converters silently drop occurrence ranges. jarvis index refuses an older scip rather than publishing a broken index.
Configuration
VariablePurpose
JARVIS_DATA_DIROverride 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.
