EXACT MCP PREVIEW
Let AI call only the exact APIs you authorized
Remote MCP projects only the ApiListings in the current API key scope. It does not select APIs, orchestrate tasks, or expand authorization. REST, SDK, and Playground use the same Production Catalog facts.
MCP is not yet publicly released
One MCP service is available to clients meeting the connection requirements; the records below are not a client allowlist. Representative Preview checks passed; production checks and failure-recovery acceptance remain before public release. REST, SDK, and Playground release according to their own acceptance results.
Current catalog version: catalog-production-2026-09-17.1
Authentication
Clients need Streamable HTTP, Bearer header authentication, and MCP tool calls. The endpoint is /mcp on the API domain. Supply the product API key as an Authorization: Bearer header through an environment variable or client secret store; never commit it.
Caching and revocation
The server revalidates the key and scope on every request. Revocation takes effect on the next request, and a cached old tool cannot exceed the current scope.
Known limitation
Two calls without an explicit idempotency_key are separate billable intents. Only a retry that reuses the same explicit key is guaranteed not to execute or charge twice.
This Preview validation
On 2026-09-15, x.users.profile@v1 was used for real calls, explicit same-key retries, and reconnection across deployments. This covers X user profiles only, not all APIs, ChatGPT, or recovery from forced in-flight interruptions.
| Client | Status | Authentication | Test date |
|---|---|---|---|
| Codex CLI 0.147.0 | Preview calls, same-key retries, cross-deployment reconnection passed | Bearer token environment variable | 2026-09-15 |
| Cursor Agent 2026.09.10-fd3934a | Preview calls, same-key retries, cross-deployment reconnection passed | Bearer header; allow the specific tool | 2026-09-15 |
| Claude Code 2.1.236 | Connection/tool discovery passed; real call unverified (on-demand follow-up) | Bearer header; model authentication unavailable in this run | 2026-09-15 |
Historical client validation
Connection, Tool List, and real calls were verified in a non-production Preview on 2026-08-17, scoped to X post search and detail. This does not cover every API in the current catalog, ChatGPT, or other client versions.
| Client | Status | Authentication | Test date |
|---|---|---|---|
| Codex CLI 0.147.0 | Earlier Preview passed (historical scope) | Bearer token environment variable | 2026-08-17 |
| Claude Code 2.1.220 | Earlier Preview passed (historical scope) | Bearer header | 2026-08-17 |
| Cursor Agent 2026.06.24-00-45-58-9f61de7 | Earlier Preview passed (historical scope) | Bearer header | 2026-08-17 |

Shared protocol tests and representative real-client checks validate integration together. Unlisted clients can use the connection requirements; support and configuration may vary. These records do not verify every client or API.
