Model Context Protocol (MCP) Server Directory

Agents that poll for new data waste 60% of their token budget on unchanged queries. This Kafka MCP Server pushes real-time events directly to agent workflows.

When your agent crashes at step 8 of a 12-step workflow, you lose everything. This Temporal MCP Server gives agents durable execution that survives crashes, deployments, and network failures.

Enterprise teams average 4,200 Notion pages per workspace, but AI agents cannot access them. This guide builds a Notion MCP server that indexes workspace content into a vector database, enables semantic search, and constructs knowledge graphs — giving Claude Desktop and Cursor full access to institutional knowledge.

MCP servers have hit 9,800+ on mcpservers.org, but observability MCP servers remain underbuilt. This guide builds a production Datadog MCP server that lets Claude Desktop and Cursor query APM traces, detect anomalies, and execute automated runbooks — reducing incident response time from 23 minutes to 90 seconds.

Sales teams spend 65% of their time on CRM data entry instead of selling. This guide builds a HubSpot MCP server that lets AI agents query deals, score leads, draft follow-ups, and automate pipeline management — giving Claude Desktop and Cursor direct CRM access for agentic sales orchestration.

Every AI agent you use has isolated memory. OzBrain's shared brain connects them all. This FastMCP Python server exposes read, write, search, and sync operations to any MCP-compatible agent — one brain, every agent.

Munder Difflin's multi-agent office needs an MCP interface. This FastMCP server exposes clone management, encrypted messaging, shared memory, and progress tracking to any MCP-compatible agent — enabling cross-tool orchestration of autonomous clones.

Agents need custom models trained on their specific tasks. This FastMCP server exposes Prime Intellect's full RL training pipeline — environment creation, hosted training, evaluation, and 1-click deployment — to any MCP-compatible agent.

Agent commerce needs programmable payment infrastructure. This FastMCP server exposes Stripe Connect's marketplace APIs to AI agents, enabling autonomous vendor onboarding, split payment orchestration, and real-time revenue tracking — all through the Model Context Protocol.

AI agents need observability data to make intelligent operational decisions. This FastMCP server exposes Grafana dashboards, alert rules, and time-series metrics to Claude and Cursor, enabling agents to self-diagnose performance issues and trigger incident response autonomously.

Agents need structured data access to manage projects, track tasks, and coordinate workflows. This FastMCP Python server exposes Airtable's full CRUD API to Claude and Cursor, enabling agents to read, create, update, and search records autonomously through the Model Context Protocol.

Multi-agent systems need reliable event coordination without a centralized orchestrator. This FastMCP Redis Streams server gives agents publish, consume, and acknowledge capabilities with consumer groups that guarantee exactly-once processing across agent fleets of any scale.
