Captapi's hosted Model Context Protocol server gives Claude, Cursor, VS Code and other MCP clients read access to public social media data through one API key. Each Captapi REST endpoint is exposed as one MCP tool that returns JSON.
This repository holds documentation and the registry manifest only. It contains no server source code.
https://api.captapi.com/mcpPOST)Authorization: Bearer or x-api-key: io.github.CDCStream/captapiPublic data only: nothing behind a login. For LinkedIn, only pages visible without signing in.
As of October 2026 the server lists 178 tools. Tool names follow _ , for example youtube_transcript, tiktok_comments or instagram_profile.
Platforms: TikTok, YouTube, Facebook, Instagram, GitHub, LinkedIn, Reddit, X (Twitter), Spotify, Threads, Rumble, Pinterest, Twitch, Google Maps, Truth Social, Kwai, SoundCloud, Bluesky, Snapchat, Kick, Amazon shop pages, and link-in-bio pages (Linktree, Linkme, Linkbio, Pillar, Komi).
Tool categories:
analytics_post, analytics_compare)account_*)Run tools/list against the endpoint for the current list with exact input schemas. Listing tools does not need a key.
Sign up at captapi.com, then create a key at captapi.com/dashboard/api-keys. New accounts get 100 free credits after email verification; no credit card is needed.
Each tool call uses the credits of the matching endpoint, listed on its page under captapi.com/apis. Calls that fail are not charged.
Keep your key out of shared config files and version control.
Replace capt_live_xxxxxxxxxxxxxxxx with your key.
claude mcp add --transport http captapi https://api.captapi.com/mcp \
--header "Authorization: Bearer capt_live_xxxxxxxxxxxxxxxx"
~/.cursor/mcp.json (global) or .cursor/mcp.json (per project):
{
"mcpServers": { "captapi": { "url": "https://api.captapi.com/mcp", "headers": { "Authorization": "Bearer capt_live_xxxxxxxxxxxxxxxx" } } } }
Claude Desktop's config file starts local (stdio) servers, so use the @captapi/mcp npm package, which calls the same API. Open Settings → Developer → Edit Config and add:
{
"mcpServers": { "captapi": { "command": "npx", "args": ["-y", "@captapi/mcp"], "env": { "CAPTAPI_API_KEY": "capt_live_xxxxxxxxxxxxxxxx" } } } }
Requires Node.js. Restart Claude Desktop after saving.
Point the client at https://api.captapi.com/mcp and send the key in a header. Either form works:
Authorization: Bearer capt_live_xxxxxxxxxxxxxxxx
x-api-key: capt_live_xxxxxxxxxxxxxxxx
Raw check with curl:
curl -s https://api.captapi.com/mcp \
-H "Content-Type: application/json" \ -H "Accept: application/json, text/event-stream" \ -H "Authorization: Bearer capt_live_xxxxxxxxxxxxxxxx" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"account_balance","arguments":{}}}'
The server is stateless: no session ID is needed, and GET on the endpoint returns 405. Without a key, initialize and tools/list work, and tools/call returns an error result asking for a key.
server.json is a copy of the manifest published to the official MCP Registry as io.github.CDCStream/captapi.
