Implementation notes
- Use this Core Features doc as a navigation page first: the local clone mirrors the source structure and links each heading back to the authoritative upstream section.
- Primary decision areas: What MCP gives you, Quick start, Catalog: one-click install for Nous-approved MCPs, Tool selection at install time, Trust model. Read those source anchors before changing installs, credentials, automation, or runtime configuration.
- Useful search signals for this doc: model, context, protocol, connect, external. These are derived from the public title and summary so the clone remains lightweight.
Decision table
Use when you need orientation for mcp (model context protocol) before applying exact upstream commands.
Open the source anchor for What MCP gives you and confirm platform-specific requirements before changing configuration.
Use the upstream page as the authority for current syntax, release changes, and security-sensitive steps.
Verification checklist
- Use this page to orient yourself within Core Features, then open the linked source page for exact current syntax.
- Start with the source section for What MCP gives you; do not rely on the local summary for commands or secrets.
- Check platform, install method, provider, and credential assumptions before changing a real environment.
- Review the source section for Quick start if the page involves setup, automation, messaging, or runtime behavior.
- After applying anything from the source, run the smallest relevant smoke test before widening scope.
Risk notes
Treat every token, OAuth grant, secret manager entry, and API key as production-sensitive. Verify least privilege and revocation before reuse.
Set provider, token, and retry limits before scaling the workflow beyond a single test run.
Check filesystem, shell, browser, repository, and server permissions before granting the agent write access.
