Quick Start
Get ContextGraph running and your first project indexed in under five minutes.
Prerequisites
- Java 17 or higher
- Git
1. Clone and build the launcher
installDist produces a native launcher script, so every later command runs directly instead of paying a Gradle startup.
git clone https://github.com/erenalpaslan/context-graph
cd context-graph
./gradlew :modules:cli:installDist
# Put it on your PATH
export PATH="$PWD/modules/cli/build/install/contextgraph/bin:$PATH"
2. Initialize your project
Run init inside the project you want to index. This creates the .contextgraph/ directory and a default config file.
cd /path/to/your/project
contextgraph init
3. Index your project
The indexer discovers supported files, parses source to a tree-sitter AST, resolves references between symbols, and writes nodes and edges to .contextgraph/graph.local.db.
contextgraph index .
# Output:
# Indexing /path/to/your/project...
# Done: 142 artifacts, 891 nodes, 1204 edges
# Skipped (unchanged): 0
Later, contextgraph refresh re-parses only what changed. If you would rather not think about it at all, enable the watcher: contextgraph config set watcher.enabled true then contextgraph watch.
4. Search the graph
contextgraph search "authentication"
# 8 results for 'authentication':
# [Class] AuthController id=io.example.AuthController confidence=1.0
# [Function] authenticate id=io.example.AuthController.authenticate confidence=1.0
# [Concept] JWT Strategy id=concept:jwt-strategy confidence=0.85
# ...
5. Generate a report
Generates GRAPH_REPORT.md (Markdown summary) and graph.html (interactive D3.js visualization) in the current directory.
contextgraph report
6. Connect to an AI agent
Start the MCP server so agents can query the graph directly. The tool that matters is contextgraph.explore: one call, one natural-language question, and the answer comes back with verbatim source rather than pointers to go read.
contextgraph serve-mcp
Add ContextGraph to your client config — point it at the launcher, not at Gradle:
{
"mcpServers": {
"contextgraph": {
"command": "/path/to/context-graph/modules/cli/build/install/contextgraph/bin/contextgraph",
"args": ["serve-mcp"]
}
}
}
See the MCP Server reference for every tool, resource and prompt the server exposes.
