Public authority for MCP server discovery

MCPserver.in — MCP Server Directory, Guides & Evidence

Public authority for Model Context Protocol discovery. Every server and every claim is backed by a primary-source evidence record.

Evidence Ledger

Every entry on this site references a primary source — a registry query, a package listing, a specification clause, or a verified repository. No marketing claims, no hosting, no pricing.

MCP Protocol & Transport

The Model Context Protocol defines how clients and servers exchange tools, resources, and prompts over JSON-RPC. Explore the protocol primitives and transport choices below.

Model Context Protocol

Model Context Protocol (MCP) explained: what it is, why it exists, how it works, and the host/client/server architecture.

MCP server

What an MCP server is, what it exposes, how local and remote servers differ, and how to choose and run one.

MCP client

What an MCP client is, the client lifecycle, tool and resource calls, and which applications function as clients.

Server Directory

Verified server entities are currently under evidence review. See the directory for the latest review status.

Frequently Asked Questions

What is MCP?
The Model Context Protocol is an open standard for connecting LLM clients to data sources, tools, and prompts. See the Learn hub for the full primer.
How is a server verified?
A server must have a published package, a public repository, and at least one verified evidence record. See .
Is this site free?
Yes. MCPserver.in is a public evidence authority. There is no hosting, no pricing, and no paid placement.
