Verified, version-pinned records of new dependency bugs. When your coding agent hits an error it cannot fix in one try, it looks the error up here before searching the web: on 56 fresh bugs it said correctly whether the bug was known or fixed 91% of the time with Cairn, 68% without.

Candidate groups, not verified unique MCPs. How grouping works
Exposes OpenAPI specifications as queryable documentation resources for LLMs, enabling semantic search, endpoint details, and deep links to Scalar docs.
Enables querying real-time, hourly, weekly, and historical weather data, as well as weather alerts, using the Caiyun Weather API.
An MCP server that provides AI agents with direct access to authoritative Cakemail API specifications, enabling accurate code generation and eliminating hallucination.
Enables AI assistants to browse, inspect, and call the Cakemail API via dynamically loaded OpenAPI spec.
Connects MCP clients to a local browser-based map editor, enabling session discovery, map state inspection, item and actor queries, actor placement and movement, selection changes, deletion, and undo/redo operations. Supports STDIO, Streamable HTTP, and legacy HTTP+SSE transports through a local WebSocket bridge.
Visual no-code generator that turns any database into multiple scoped MCP servers — one per access group, with PII masking and fail-closed query scoping built in.
MCP server for the Calcifier smart camping lamp, enabling control of lamp state, brightness, color temperature, mode, and battery charging via natural language with Claude.
Calibrd Agent scores a job against your CV from inside your assistant: fit, seniority gaps, ATS/recruiter CV read, and predicted interview questions. Reports are free (3/day); cover letter and a time-boxed pass unlock when you ask, voice mock stays in Calibrd.com/workspace.
Enables an AI assistant to place user-approved phone calls in the callee's language through your own Bland or Twilio account, with language detection, script generation, cost estimates, and safety guard rails. Includes a preview-then-confirm gate, plus call status, transcripts, and summaries.
Your AI agent phones businesses for you: books, reschedules, cancels, asks, and waits on hold.
Enables MCP clients to place real phone calls to businesses in the US and Canada, navigating phone menus, waiting on hold, asking the agent mid-call for information, and returning structured answers with transcripts. Supports booking, quotes, cancellations, and multi-business calls in parallel.
CallHub MCP is a Python-based tool that allows you to interact with the CallHub API through Claude. This tool provides a comprehensive set of functions for managing contacts, phonebooks, agents, teams, campaigns, and other CallHub resources.
Static preflight safety gate for MCP servers — scan configs before you run them. Never executes.
A single MCP server that provides a provider-neutral 14-tool contract for telephony operations (calls, SMS, recordings, transcripts, and number lifecycle), supporting hosted, fully local, or bring-your-own-key backends.
One shared memory for every AI you use, in plain Markdown files you own. Teach one AI something and the rest know it, with per-AI folder permissions so each assistant only sees what you allow.
Enables AI agents to make instant calls, manage CEMAS emergency notifications, pick Edge TTS voices, manage agents, leads, scheduled calls, and query call history via the CallRemind REST API.
Enables AI agents to discover each other by @handle, exchange consent-based message requests, and record auditable, tamper-evident ledger entries through MCP.
Provides an MCP server that automatically exposes API routes as MCP tools with input validation and authentication, enabling AI agents to call the same handlers as HTTP RPC.
Enables AI assistants to make phone calls via CallZero service, with tools for call management, templates, and memory.
Gives AI agents governed, read-only access to product marketing intelligence such as positioning, messaging, win/loss, and competitive briefs, plus persona-based draft reviews.
A hosted multimodal RAG MCP server that enables natural language queries over text and visual content (PDFs, images, etc.) with verifiable citations, easily run via npx with a Calypso API key.
Enables agents to access live DeFi, social intelligence, risk, and API documentation tools with a caller-supplied API key.
A lightweight server that exports CAMEL framework toolkits as MCP-compatible tools.

Default browsing excludes 2,356 specialized utility groups across the catalog. They remain available through keyword search and direct links. This editorial filter does not change the indexed totals or establish publisher quality.
Categories currently cover records matched to our reviewed catalog; other listings remain Uncategorized. Source-only projects have no generated connection option. Browse reviewed official MCPs →
- Glama connectors
API result set; pagination may cap at approximately 1,000 connectors. Not exhaustive.
- Glama source code
Complete chronological source-code catalog response; includes source-reported author classifications, not publisher attestations or ready-to-use endpoints.
- Official MCP Registry
Complete paginated registry response; registry membership is not publisher verification.
- Claude connector directory
Complete public Claude directory MCP components. Source tiers, tools, icons and sign-in hints are declarations, not publisher or runtime verification.
- API Tracker · publisher documentation
Publisher-documented remote presets, local servers and discovery-only announcements reviewed by API Tracker. Discoverability does not establish connection readiness.
- Slack MCP directory
Reviewed additions discovered through the public Slack Marketplace MCP category. Complete discovery inventory is retained separately; membership does not prove external-client compatibility.
Listings are grouped by exact public endpoints, exact package sets, or explicit reviewed identity bindings. Shared names or repositories alone do not merge implementations. Official includes publisher evidence and accepted source author classifications. It does not mean independently verified, runtime-tested or security-certified.
