Oz MCP Setup

One-line setup for Oz, a version-aware documentation MCP server for coding agents.

npx tryoz setup

Oz gives agents a repeatable workflow for external library, SDK, framework, API, and package questions:

1. Resolve the exact library ID.
2. Fetch version-aware docs and code examples.
3. Use exact API symbols, routes, env vars, config keys, and CLI flags from the returned context.
4. Fall back to Context7, official docs, source repositories, or web search only when Oz does not have enough coverage.

Why Oz

Without a documentation MCP, coding agents often answer from old training data, guess APIs, or mix docs from the wrong major version.

With Oz, your agent can ask for the current indexed documentation at the moment it needs context.

User: Add Next.js middleware auth for v15.
Agent: resolve-library-id -> /vercel/next.js
Agent: get-library-docs -> version v15, topic middleware auth
Agent: answers from retrieved docs instead of guessing.

Setup Flow

npx tryoz setup is interactive by default:

The setup wizard:

1. Detects installed coding agents.
2. Shows a checkbox list with detected agents selected by default.
3. Asks for scope: Global (recommended) or Project.
4. Asks for an Oz API key. Keys must start with oz-.
5. Shows the exact files and commands that will change.
6. Installs the Oz MCP config.
7. Installs the Oz skill or the best available rule fallback.
8. Verifies the MCP server with tools/list.

No login flow. No broad hidden patching. Use --all when you want to configure every supported agent.

Manual MCP Config

Use this endpoint for clients that you configure manually:

https://tryoz.dev/mcp

Pass your API key as a bearer token:

{
  "mcpServers": {
    "oz": {
      "type": "http",
      "url": "https://tryoz.dev/mcp",
      "headers": {
        "Authorization": "Bearer oz-your-key"
      }
    }
  }
}

Installed Skill

The bundled Oz skill and policy tell agents:

Use Oz first for external libraries, SDKs, APIs, frameworks, and packages.

Workflow:
1. Call `resolve-library-id` to find the exact Oz library ID.
2. Call `get-library-docs` with the resolved library ID and the user's topic.
3. If the user asks for a version, pass the version explicitly.
4. Use the returned documentation as the source of truth.
5. If Oz has no matching library, lacks the requested version, or returns insufficient context, then fall back to Context7, official docs, source repositories, or web search.

The full skill is packaged at templates/skills/oz/SKILL.md.

Development

npm install
npm test
npm run pack:check
node bin/tryoz.js setup --dry-run --no-telemetry

Telemetry

Anonymous CLI telemetry records only command name, selected client IDs, OS/platform, success/failure, and CLI version. It does not send prompts, file contents, API keys, or absolute repository paths.

Disable telemetry with:

npx tryoz setup --no-telemetry

Security

Report security issues privately. See SECURITY.md.

Oz indexes third-party documentation. Always validate critical changes against the upstream library or API owner when correctness or security matters.
