Smithery

Smithery is a platform for discovering, deploying, and managing Model Context Protocol (MCP) servers and skills. It operates a public registry of community-built MCP extensions that AI agents can use to access external tools, data sources, and services, plus a Connect gateway that bundles connections in a namespace behind a single MCP endpoint at mcp.smithery.run. The platform exposes APIs for server registry browsing, server deployment, skill publishing, namespace management, scoped service tokens, connection lifecycle, trigger subscriptions, and an MCP transport endpoint for AI-agent integration.

Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.

Kin Score

API Evangelist profiles Smithery the way a machine reads it — 32 machine-readable artifacts across 9 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Smithery scores 60.1/100 (strong), with a separate agent-readiness read of 60/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Smithery

Each block below is one kind of artifact we hold for Smithery. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 9

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.

Smithery connect API

The connect API from Smithery — 12 operation(s) for connect.

Smithery connect.mcp API

The connect.mcp API from Smithery — 1 operation(s) for connect.mcp.

Smithery domains API

The domains API from Smithery — 2 operation(s) for domains.

Smithery Health API

The Health API from Smithery — 1 operation(s) for health.

Smithery namespaces API

The namespaces API from Smithery — 3 operation(s) for namespaces.

Smithery organizations API

The organizations API from Smithery — 2 operation(s) for organizations.

Smithery servers API

Browse the MCP server registry, manage server configuration, and handle deployments

Smithery skills API

Discover and search reusable prompt-based skills for MCP servers

Smithery tokens API

The tokens API from Smithery — 1 operation(s) for tokens.

Open Collections 2

Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

MCP Servers 2

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Pricing Plans 1

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.

Published pricing tiers and plan structures.

Rate Limits 1

Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

Documented rate limits and quota policies.

FinOps 1

Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Cost, billing, and metering signals for API financial operations.

Semantic Vocabularies 1

JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

JSON Schema 2

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

Examples 7

Real request and response payloads are what turn a spec from abstract into obvious — and they're one of the twelve things an agent needs to call an API correctly on the first try.

Security Posture 2

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Agentic Access 1

An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
