Arcade.dev - Tool Calling platform for Agents
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"arcade-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

It powers the 7,500+ prebuilt tools across 81 MCP servers at [Arcade.dev](https://arcade.dev), and is open-sourced so you can build your own. Use it when you need MCP tools that aren't already in the prebuilt catalog: internal APIs, custom OAuth providers, domain-specific integrations. **Highlights:** - Decorator API covering the full MCP spec: tools, resources, prompts, sampling, elicitation, progress, logging. - [Authorized tool calling](#authorized-tool-calling). Declare `requires_auth=GitHub(scopes=["repo"])` and Arcade handles OAuth, token refresh, and per-call scoping. The client and the LLM never see the token. - Vendor-neutral. Any MCP client, any LLM, any agent framework (LangChain, Mastra, Pydantic AI, CrewAI, Google ADK, OpenAI Agents). - `arcade evals` for testing tool-call accuracy against real LLMs. - `arcade deploy` for one-command hosting on Arcade Cloud. ## Authorized tool calling Tools can declare: 1.
