codebase-memory-mcp

Local code intelligence for developers and AI agents. CBM connects source code, documentation and infrastructure in a persistent knowledge graph. Explore through MCP, the CLI or CBM Lens to find code, trace dependencies and deployments, and understand what a change affects.

This npm wrapper downloads, verifies and caches the native executable, its authenticated integration asset and the content-addressed Lens frontend pack. Node.js manages installation and launch; the graph is processed locally without a hosted service or API key. The installer offers 45 client integration targets, with capabilities that vary by client.

Installation

npm install -g codebase-memory-mcp

The runtime set for your platform is downloaded automatically at install time. There is one composition per platform and the graph UI is always included — the former CBM_VARIANT=ui opt-in is obsolete.

For testing, CBM_DOWNLOAD_URL overrides the download base URL (default https://github.com/DeusData/codebase-memory-mcp/releases/download/v<version>): the archive and checksums.txt are fetched from <CBM_DOWNLOAD_URL>/<file>. It must be https://, or plain http:// to exactly localhost, 127.0.0.1, or [::1] (optional port; no proxy, no redirects).

Then configure your coding agents:

codebase-memory-mcp install

Restart your agent and ask it to "Index this project". Use codebase-memory-mcp daemon start --open to open CBM Lens. Supported integrations also install graph instructions, skills, agent profiles and context hooks; consult the full client matrix for differences.

Why codebase-memory-mcp

• Connected repository knowledge — source symbols and calls, documentation sections and references, configuration, infrastructure and cross-service links.
• Plug and play — verified native runtime sets for macOS (arm64/amd64), Linux (arm64/amd64), and Windows (arm64/amd64). No Docker or API keys; Node.js owns package download, cache repair, and launch.
• Broad language and format support — bundled parsers, with deeper semantic resolution for supported language families. See the language reference for coverage.
• Focused context — retrieve symbols, relationships and bounded source excerpts instead of repeatedly reading whole files. Savings depend on the task and workflow.
• CBM Lens — explore source, architecture, call paths, decisions and index coverage in a local browser workspace.
• Smart CI — experimental change-aware test selection for supported C/C++ test runners, using graph relationships and admitted per-test coverage. Missing evidence broadens execution. See the Smart CI guide.
• 45 supported automatic/conditional client surfaces — install configures the appropriate MCP, durable-context, and documented hook surfaces without widening client permissions.
• Detected automatically (39) — Claude Code, Codex CLI, Gemini CLI, Zed, OpenCode, Antigravity, Aider, KiloCode, VS Code, Cursor, Windsurf, Augment / Auggie, OpenClaw, Kiro, Junie, Hermes, OpenHands, Cline, Warp, Qwen Code, GitHub Copilot CLI, Factory Droid, Crush, Goose, Mistral Vibe, Grok Build, Qoder CLI, Kimi Code CLI, GitLab Duo CLI, Rovo Dev CLI, Amp, Devin CLI / Local, Tabnine, Amazon Q Developer IDE, CodeBuddy Code CLI, IBM Bob Shell, Pochi, Pi, and Oh My Pi (omp).
• Conditional or explicit (6) — Continue / cn, Visual Studio, TRAE, Roo Code, IBM Bob IDE, and Sourcegraph Cody. Bob IDE is touched only when ~/.bob/mcp.json already exists.
• New documented adapters — CodeBuddy uses ~/.codebuddy/.mcp.json while preserving active older files; Bob Shell uses ~/.bob/mcp_settings.json; Pochi uses the mcp section in ~/.pochi/config.jsonc; Amazon Q Developer IDE defaults to ~/.aws/amazonq/default.json while preserving either documented alternative.
• Lifecycle hooks stay conservative — Kimi uses UserPromptSubmit; on macOS/Linux, GitLab Duo gets a fail-open user SessionStart, while Devin gets UserPromptSubmit, PostCompaction, and a deduplicated SessionStart when Claude does not already provide it. Qoder, GitLab Duo, Devin, and Factory hooks are withheld on Windows without a documented shell/executor contract. Cline's auto-activating file hooks are withheld because their context output is not reliably consumed, CodeBuddy beta hooks are not auto-installed, and Cursor context hooks remain withheld.
• Subagent access is explicit — Claude, Gemini, Kiro, Qwen, CodeBuddy, KiloCode, Mistral Vibe, Grok Build, Qoder, Junie, and Factory get documented graph profiles with the narrowest tool/server filters their schemas support. KiloCode and Vibe enumerate read-only query tools rather than using server wildcards. Cursor, Rovo, Pochi, and Cline use explicit parent handoff where child MCP is unavailable or unsafe; IBM Bob receives no invented hook or agent.
• Manual, UI, cloud, or repository-managed (not counted) — Qodo, Warp MCP, JetBrains AI/ACP, GitHub Copilot coding agent, Jules, CodeRabbit, Replit, BLACKBOX AI, Plandex, and SWE-agent. Warp is counted above for its detected skill installation; its MCP connection remains manual.
• 17 MCP tools — search, trace, architecture, impact analysis, Cypher queries, dead code detection, cross-service HTTP linking, ADR management, and more.

Supported Platforms

OS	Architecture
macOS	arm64, amd64
Linux	arm64, amd64
Windows	arm64, amd64

Usage

codebase-memory-mcp install          # configure all detected coding agents
codebase-memory-mcp --version
codebase-memory-mcp --help
codebase-memory-mcp update           # update to latest release
codebase-memory-mcp uninstall        # remove agent configs; keep indexes by default

Uninstall keeps project indexes with --yes, --no, or noninteractive input unless you explicitly add --delete-indexes. An interactive terminal without the flag asks separately and defaults to keeping them. --delete-indexes overrides --no; add --dry-run to preview without changing files. Kept indexes remain in the cache directory printed by uninstall.

CLI Mode

Every MCP tool is also available directly from the command line:

codebase-memory-mcp cli index_repository '{"repo_path": "/path/to/repo"}'
codebase-memory-mcp cli list_projects '{}'
# Replace PROJECT with the indexed project name returned above.
codebase-memory-mcp cli search_graph '{"project":"PROJECT","name_pattern":".*Handler.*","label":"Function"}'
codebase-memory-mcp cli trace_path '{"project":"PROJECT","function_name":"main","direction":"both"}'
codebase-memory-mcp cli get_architecture '{"project":"PROJECT"}'

MCP Tools

Category	Tools
Indexing and coverage	index_repository, list_projects, delete_project, index_status, check_index_coverage
Search and source	search_graph, search_code, get_code_snippet, get_file_outline
Relationships and changes	trace_path, query_graph, detect_changes, compare_graphs

Performance

Performance and context savings depend on the repository, query, machine and agent workflow. See the scoped benchmark results and methodology for recorded measurements and limitations.
