  • MCP reference servers · dev_tool · oss · MIT to Apache-2.0 transition

    Reference MCP server implementations you can run yourself.

    Limits: none stored.

    Source · asOf 2026-10-25 · Fetched LICENSE says the project is moving from MIT to Apache-2.0. Not a hosted free quota. Re-fetched twice 2026-10-25 (~10 s apart, plain curl, no login): GitHub blob page HTTP 200, no redirect (page chrome differs between fetches); raw LICENSE fetched twice too, HTTP 200, byte-identical: 'The MCP project is undergoing a licensing transition from the MIT License to the Apache License, Version 2.0'. Still states 'All new code and specification contributions to the project are licensed under Apache-2.0.' License unchanged.

  • Official MCP Registry · dev_tool · oss · MIT to Apache-2.0 transition

    Public metadata registry of MCP servers. The MCP Registry provides an unauthenticated read-only REST API (GET /v0.1/servers) at https://registry.modelcontextprotocol.io. No price is published on the fetched docs.

    Limits: none stored.

    Source · asOf 2026-10-24 · Docs fetched 2026-10-24: 'The MCP Registry provides an unauthenticated read-only REST API that aggregators can use to populate their data stores.' 'The MCP Registry is currently in preview.' It 'does not provide uptime or data durability guarantees'. Publishing requires namespace-based authentication (https://github.com/modelcontextprotocol/registry/blob/main/docs/reference/api/official-registry-api.md). Neither page publishes a price or a numeric rate limit, so the hosted API is not stored as a $0 price or a quota. cost oss is the registry repo LICENSE (https://github.com/modelcontextprotocol/registry/blob/main/LICENSE, fetched 2026-10-24): 'The MCP project is undergoing a licensing transition from the MIT License to the Apache License, Version 2.0'. Not a substitute for Depot picks.

Reference (docs, public datasets and benchmarks) (2)

  • Model Context Protocol specification 2026-07-28 · free_docs · free · Apache-2.0

    The MCP specification, including tool and schema shapes, published at no charge.

    Limits: none stored.

    Source · asOf 2026-10-25 · Spec revision date is 2026-07-28. Repo LICENSE text fetched for the servers and registry repos describes an MIT to Apache-2.0 transition; this row does not restate unpublished draft text. Re-fetched twice 2026-10-25 (~10 s apart, plain curl, no login): the spec page answered HTTP 200, byte-identical (title 'Specification - Model Context Protocol', navigation links /specification/2026-07-28/basic/index; the page itself carries no license text). The spec repo LICENSE https://raw.githubusercontent.com/modelcontextprotocol/modelcontextprotocol/main/LICENSE was also fetched twice (HTTP 200, byte-identical): 'All new code and specification contributions to the project are licensed under Apache-2.0.' License unchanged.

  • Agent Skills specification · free_docs · free

    Public Agent Skills docs index, including the specification links.

    Limits: none stored.

    Source · asOf 2026-10-25 · llms.txt fetched 2026-10-03 lists the Agent Skills docs. No license line was in that file. The HTML specification page also returned 200. License left null. Re-fetched twice 2026-10-25 (~10 s apart, plain curl, no login): HTTP 200, byte-identical; the file still starts '# Agent Skills' and links [Specification](https://agentskills.io/specification.md), and still has no license line, so license stays null.
