Install OpenCodeHub for any MCP agent
This page is editor-agnostic. It gets codehub on your PATH, indexes a
target repo, and points you at the per-editor wiring. If you only use
Claude Code, you can stop after step 5 — codehub init writes the
right config and links the plugin.
1. Prerequisites
Section titled “1. Prerequisites”- Node 22 (with native tree-sitter) or 24 (WASM default).
- pnpm 10 or newer.
- git.
- Optional:
mise— recommended for the per-project tool versions and thecli:linktask.
2. Clone and install
Section titled “2. Clone and install”git clone https://github.com/theagenticguy/opencodehubcd opencodehubpnpm install --frozen-lockfile3. Put codehub on your PATH
Section titled “3. Put codehub on your PATH”mise run cli:linkcli:link resolves the workspace @opencodehub/cli package and links
its bin into your shell. Verify with codehub --version.
If you do not use mise, run pnpm -F @opencodehub/cli link --global
inside the checkout.
4. Initialize a target repo
Section titled “4. Initialize a target repo”cd /path/to/your/repocodehub initcodehub init is idempotent. It writes:
.mcp.json— local-scope MCP server entry pointing at the codehub binary. Picked up by Claude Code, Cursor (when symlinked into.cursor/mcp.json), and any other agent that reads the standard project-scope MCP file..claude/— links the OpenCodeHub plugin so Claude Code gets slash commands, thecode-analystsubagent, and 11 skills..gitignore— appends.codehub/so the local graph and temporal store stay out of version control.opencodehub.policy.yaml— seed policy file (license tiers, risk thresholds). Edit to taste, commit if you want repo-wide policy.
5. Build the first index
Section titled “5. Build the first index”codehub analyzeExpect 30 seconds for a small TypeScript service, 1–3 minutes for a
medium monorepo, 5–10 minutes the first time on a large repo (after
which incremental analyzes are sub-second per file). Output is written
to .codehub/ next to the project root.
The default storage backend is the graph database backend
(graph.lbug + temporal.duckdb). DuckDB is the legacy fallback.
Set CODEHUB_STORE=duck to force the legacy single-file layout, or
CODEHUB_STORE=lbug to require the graph backend. See
ADR 0013.
6. Verify the install
Section titled “6. Verify the install”codehub doctorcodehub doctor prints the active toolchain: tree-sitter native
binding, DuckDB native binding, optional graph-database binding, and
which embedding backend is in effect (SageMaker → HTTP → local ONNX,
in that precedence). All three native bindings should report OK on
Node 22; on Node 24 the WASM parser is the default and the native
tree-sitter binding may be missing — that is expected.
7. Wire your editor
Section titled “7. Wire your editor”The per-editor pages give you the config snippet, the path it goes into, and the verification step.
