ontomics provides a semantic indexing solution for codebases, enabling efficient querying of domain concepts and relationships with significantly reduced tool calls and token usage.
From the registry: Index your codebase's domain knowledge. 20x fewer tokens, 10x faster.
Install & configure
Prerequisites
- requiredInstall ontomicsInstall via npm, Homebrew, or shell installer.
$ npm install -g @ontomics/ontomics - requiredGit repositoryontomics requires a git repository (.git directory). Pass --force to index a non-git directory.
Install in your client
Paste into the AI you're chatting with — it will figure out the rest
Please install the `ontomics` MCP server into my current AI client (that's you).
Required prerequisites (do these first if not already done):
- **Install ontomics** — Install via npm, Homebrew, or shell installer. Run: `npm install -g @ontomics/ontomics`
- **Git repository** — ontomics requires a git repository (.git directory). Pass --force to index a non-git directory.
Canonical MCP server config (stdio transport):
- command: `npx`
- args: ["-y","@ontomics/ontomics","--repo","."]
Note: Auto-detects repo and indexes on first run. No API keys — BGE-small and CodeRankEmbed models downloaded once, cached locally. Index at <repo>/.ontomics/index.db.
Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.Note: Auto-detects repo and indexes on first run. No API keys — BGE-small and CodeRankEmbed models downloaded once, cached locally. Index at <repo>/.ontomics/index.db.
