Model Context Protocol (MCP)
Open protocol for LLM clients to talk to external tools and data sources. The 'USB-C for AI' that became the default in 2026 — supported by Anthropic, OpenAI, and Google DeepMind, with 500+ public MCP servers covering GitHub, Slack, Postgres, Stripe, Figma, Docker, Kubernetes, and 200+ more. Major clients: Claude Desktop, Cursor, Windsurf, Goose CLI. Works with any LLM that supports function calling, including local Ollama models.

Stack & relationships
How Model Context Protocol (MCP) relates to other entries in the catalog — recommended pairings, alternatives, dependencies, and edges to avoid. Each edge carries a one-line operator note from our editorial team.
Works with
- Integrates withClaude Code
First-class MCP support — strict implementation of the protocol. Configure servers in the project's MCP config.
- Integrates withClaude Desktop
The original MCP host. Strictest spec implementation; the reference for server developers verifying compatibility.
- Integrates withGoose
Block's Goose treats MCP as a first-class extension surface. Strong support for both stdio and remote MCP servers.
- Integrates withOpenClaw
OpenClaw's MCP support is first-class as of v1.x — both stdio and remote MCP. The reason most newer servers test against it.
- Integrates withGoose
Goose treats MCP as the primary extension surface. Strong support for both stdio and remote servers; good fit if MCP-heaviness is core to your workflow.
- Integrates withOpenHands
MCP is one of several tool transports OpenHands speaks — the protocol is supported but not the only path.
- Integrates withOpen WebUI
Open WebUI's pipelines feature now supports MCP transports. Less mature than Claude Desktop's MCP host but improving.
- Integrates withAnythingLLM
AnythingLLM's MCP support landed in 2025-2026. Lets workspaces wire MCP servers as agent tool surfaces — turns AnythingLLM into an agent front door.
Avoid pairing with
- Works poorly withMCP PostgreSQL Server
Older Postgres MCP versions had a statement-stacking SQL injection that bypassed the read-only wrapper. Pin a current version AND run with a least-privilege DB role.
Pros
- Open standard — no vendor lock-in
- 500+ public servers as of early 2026
- Backed by all three major frontier labs
- Works with local LLMs (Ollama, Qwen)
Cons
- Permissioning/auth still maturing
- Quality of community servers varies
- Adds a network round-trip per tool call
