Smithery
Search, connect and call MCP servers and agent skills, now part of Arcade
Overview
Smithery is a registry and gateway for Model Context Protocol servers and agent skills — about 18,000 servers and 24,000 skills — with search, managed OAuth, persistent connections and a CLI, acquired by Arcade.dev in August 2026. Free for 50,000 calls a month; pay as you go from $10.

What you can produce with Smithery
- Searchable registry of ~18,000 MCP servers
- Agent-skills catalog (~24,000) alongside servers
- Gateway with managed OAuth, tokens and persistent connections
- Uplink for exposing local MCP servers without deploying
- CLI (AGPL-3.0, now under Arcade) for install and connection management
- Keyword and semantic search across the registry
Smithery is the biggest catalogue of MCP servers and agent skills we know of, and it has grown from a directory into a gateway: search by intent, connect through managed OAuth and persistent sessions, and call tools through one endpoint, with a free tier generous enough for experiments and pay-as-you-go from $10 a month. Two things changed in 2026. Arcade.dev acquired it in August, so its roadmap now sits inside a larger agent-runtime company, and it has moved away from hosting servers itself toward proxying ones you host. Its 2025 build-system flaw was fixed within days with no sign of exploitation, but third-party servers in any registry can carry hidden instructions, so review what you connect. Strong for developers wiring agents to many tools; enterprises should look at Arcade's governance features too.
What we found
Smithery is a registry for Model Context Protocol servers and agent skills: developers publish MCP servers there, and AI clients and agents search it, connect and call tools through Smithery's gateway. The registry now lists about 18,000 servers and 24,000 skills, searchable by keyword or by meaning, and the platform handles the awkward parts of connecting — managed OAuth, tokens and sessions through a Connect API, persistent connections, webhook triggers, token scoping, verification of official vendor servers, and Uplink, which exposes a server running on your own machine without deploying it. Its command-line tool manages installs and connections.
Ownership changed in August 2026, when Arcade.dev, which builds a runtime for enterprise AI agents, acquired Smithery; co-founder Anirudh Kamath joined Arcade, and the CLI repository moved to Arcade's GitHub under the AGPL-3.0 licence. Smithery was co-founded by Henry Mao, its chief executive, and Kamath. Hosting has also shifted: Smithery now mainly lists and proxies servers you host yourself, or packaged local bundles, with hosted releases limited to uploaded JavaScript modules.
Security history deserves an accurate account. In June 2025, researchers at GitGuardian found a path-traversal flaw in Smithery's build system that exposed a fly.io credential giving access to more than 3,000 hosted servers and the secrets they held. Smithery fixed it within five days of discovery, and GitGuardian, publishing in October 2025, reported no evidence of exploitation. A scan of 100 Smithery-listed servers published in April 2026 by a security-tool vendor flagged 22 with findings, most commonly instructions hidden in tool descriptions, while acknowledging some false positives. Third-party servers in any registry deserve review before you connect them.
Listing a server is free. Consuming servers costs by RPC call: Hobby is free for 50,000 calls a month and three namespaces, Pay as you go costs $10 a month for 100,000 calls and then $0.10 per thousand, and Custom adds rate limits, an uptime SLA and Slack support. It remains the largest MCP directory we know of, now under a new owner.
