MCP Servers & Skills

Beyond the curated OAuth connectors - browse thousands of MCP servers and a 90,000-entry Skills catalog, and let OpenHuman act as an MCP server itself.

The one-click OAuth integrations are the curated path. Beyond them, OpenHuman opens up the wider open-tooling ecosystem in two ways: the Model Context Protocol (MCP) registry and the Skills catalog. OpenHuman can also expose itself as an MCP server to other clients.

MCP servers (thousands)

OpenHuman has a built-in MCP registry that browses the open MCP ecosystem and lets you install servers locally as new typed tools for the agent.

  • Two upstream registries, merged. Discovery fans out in parallel to Smithery.ai and the official registry.modelcontextprotocol.io, then merges the results: thousands of servers across both.

  • Search β†’ install β†’ connect. Search the catalog, view a server's details, and install it. A local install spawns the server as a stdio subprocess; deployed servers connect over HTTP.

  • Supervised connections. Installed servers are persisted in a local SQLite store (mcp_clients/mcp_clients.db) with their command, args, and transport. A supervisor loop keeps enabled servers connected, probing every ~60s with per-server exponential backoff.

Once connected, an MCP server's tools are available to the agent exactly like native tools.

The catalogs are open-ended and grow on their own. The "5,000+" figure reflects the combined Smithery + official ecosystem size, not a fixed list baked into OpenHuman.

OpenHuman as an MCP server

OpenHuman can run the other way around, too. openhuman-core mcp exposes OpenHuman over stdio as an MCP server, offering read-only tools (memory search / recall, Memory Tree browsing, and optional web search) to clients like Claude Desktop. See MCP Server for setup.

Skills (90,000-entry catalog)

Skills are a large, browsable catalog of agent skills (SKILL.md-style capability bundles) aggregated from multiple upstream sources (HermesHub, ClawHub, LobeHub, and more).

  • One aggregated catalog. Sourced from HermesHub (configurable via OPENHUMAN_SKILL_REGISTRY_CATALOG_URL), the catalog runs to roughly 90,000 entries. Each entry carries id, name, description, source, author, version, tags, platforms, a download URL, and license.

  • Cached and fast. The catalog is fetched on boot in the background (without blocking startup), cached locally at ~/.openhuman/skill-registry/cache.json with a ~1-hour TTL and served stale-while-revalidate. A single-flight gate prevents duplicate downloads of the large catalog.

  • Metadata-first. OpenHuman's in-app skills runtime (the old QuickJS sandbox) has been removed. Skills are now a metadata catalog you browse and install from the Connections β†’ Skills tab, not code executing inside the app. Availability varies per entry: some expose a direct SKILL.md download, others point to external hosting.
