Best Developer Tools MCP Servers

For AI agents — MCPBundles directory (search all MCP servers)

General MCP server search (Directory API v1 — use this before per-server calls):
GET https://www.mcpbundles.com/api/directory/v1
GET https://www.mcpbundles.com/api/directory/v1/search?q=<query>&limit=30
Query q (or search) needs at least 3 characters (example: q=stripe).
Use cursor from the JSON response for the next page.
Optional search filters: connect_path, harvest_only, catalog_listing, kind, registry_eligible=true.
Each hit includes directorySlug and pageUrl — open pageUrl for humans; use directorySlug in API paths below.

Per-server tool run (replace {slug} and {tool} after search):

GET https://www.mcpbundles.com/api/directory/v1/servers/{slug}?live=1 (optional live tool refresh)
