OpenAPI Specification
openapi: 3.2.0
info:
title: FastDrop Subregistry API
version: 1.3.0
description: 'FastDrop is the liveness layer for agent-ready software: the official MCP Registry authenticates who published a server, FastDrop probes whether it still answers, and publishes the tools each endpoint actually returned.
Three surfaces, one API:
- `POST /mcp` - a Streamable HTTP MCP server (JSON-RPC 2.0). Read tools (list_launches, get_engagement_feed, get_product, get_maker, search_products, find_tools, list_reviews, list_comments, get_launch_day_status, get_install_config, find_alternatives, compare_products, find_deals) are unauthenticated; write tools (submit_product, update_product, toggle_vote, post_review, post_comment, recheck_mcp, check_submission_status, invite_collaborator, get_my_stats, get_inbox, mark_notifications_read, get_launch_kit, follow, list_following, list_webhooks, create_webhook, delete_webhook, test_webhook, update_profile, set_deal, set_open_to) require a Bearer token. Prompts (prompts/list, prompts/get): launch_my_product, daily_engagement, find_tools_for, launch_report.
- `GET /v0.1/servers` - an MCP Registry-compatible subregistry (OpenAPI shape) with a `dev.fastdrop/verification` liveness block in `_meta`. Unauthenticated, cursor-paginated.
When to use this API: discover agent-ready products by probed capability (not marketing tags), check whether an MCP endpoint currently answers, submit or update your own listing programmatically, and poll submission status. When NOT to use it: identity verification of server publishers (that is the official registry at registry.modelcontextprotocol.io) and human browsing (use the website).

description: FastDrop API key (starts with fd_). Create one in the dashboard at /app/developer (Developer tab). Grants read access plus write access to your own submissions, votes, reviews, and comments over /mcp. Revoke any time; no scope narrowing on keys - prefer OAuth when a client only needs MCP access.
FastDropOAuth:
type: oauth2
description: OAuth 2 for MCP clients (RFC 8414 metadata at /.well-known/oauth-authorization-server, protected-resource metadata at /.well-known/oauth-protected-resource/mcp). Public clients supported (empty client secret on the token endpoint).

authorizationUrl: https://fastdrop.dev/api/auth/oauth2/authorize
tokenUrl: https://fastdrop.dev/api/auth/oauth2/token
refreshUrl: https://fastdrop.dev/api/auth/oauth2/token
scopes:
mcp: Call the FastDrop MCP server (/mcp) on behalf of the signed-in user. Read tools plus their own submissions, votes, reviews, and comments - nothing else.
offline_access: Receive refresh tokens so a long-lived agent session can renew access without re-consent.
