Send the handshake to `https://mcp.courier.com/mcp` over streamable-http. Servers on the 2026-07-28 revision answer `server/discover`; older servers answer `initialize`. 2. Send `tools/list`, then `resources/list` and `prompts/list` if the capabilities name them. 3. Send no token. The connector sent none and the server answered, so any MCP client can read this list. 4. Calling a tool is a separate step this directory never takes. See [OAuth for MCP: client ID metadata documents and dynamic registration](https://agentmcpdirectory.com/guides/oauth-for-mcp-cimd-dcr/) for how each route works. ## CLI No CLI is on record for Courier. The directory checks a package only where a source names one, so this is a floor: a company can ship a command line that no source read for this edition mentions. See [shipping a CLI agents can use](https://agentmcpdirectory.com/guides/ship-a-cli-for-agents/). ## Other agent surfaces | Surface | Result | | --- | --- | | OpenAPI file | No OpenAPI file at the root paths checked. | | WebMCP in the initial HTML | Not detected on the home page by the shared crawl. | | MCP discovery file | Not found (the crawl got a non-200 answer). | | A2A agent card | Not found (the crawl got a non-200 answer). | | A2A agent card (older path) | Not found (the crawl got a non-200 answer). | | agents.json | Not found (the crawl got a non-200 answer). | | OAuth authorization server metadata | Not found (the crawl got a non-200 answer). | | NLWeb endpoint | Not checked in this edition. | ## Registry listings | Registry | Listed | | --- | --- | | Official MCP Registry | No | | GitHub MCP Registry | No | | awesome-remote-mcp-servers | No | | Smithery | Not checked: Smithery's listing pages and search API were unavailable on 4 November 2026. | | Glama | Not checked: Glama's API needs a key and attribution terms. | Edition 4 November 2026 Method [How rows are verified](https://agentmcpdirectory.com/method/) Data [CSV and JSON](https://agentmcpdirectory.com/data/) Markdown [This page as markdown](https://agentmcpdirectory.com/directory/courier-com/index.md) ## Sources - [Ora score page for courier.com](https://ora.ai/score/courier.com?utm_source=agentmcpdirectory.com&utm_medium=referral&utm_campaign=entry), read 5 November 2026 (vendor-published score, scanned 22 August 2026, read from GET /api/score) - [Where Courier was found](https://ora.ai/leaderboard?utm_source=agentmcpdirectory.com&utm_medium=referral&utm_campaign=entry), read 4 November 2026 - [Courier website](https://courier.com), read 4 November 2026 - [Official MCP Registry API, the registry read for this edition](https://registry.modelcontextprotocol.io/v0/servers), read 4 November 2026 Last reviewed 5 November 2026
