About mcp servers

What is an MCP server?

An MCP server is a connector built on the open Model Context Protocol: it exposes a set of tools, resources, and prompts that an AI client like Claude or Cursor can call to act on real systems — files, APIs, databases, and SaaS apps.

Every MCP server on Sigrix lists the tools it exposes, the platforms it has been tested with, and how to connect it, so you know exactly what your AI can do before you install it.

Compare MCP servers by the integration they add, the transport they use, the keys they require, and price — then point your MCP client at the one you pick and go.

People searching for MCP servers usually want a ready-built connector they can point an MCP client at, with a clear list of the tools it exposes and the keys it needs.

What's inside an MCP server

01
Tools your AI can call
The server exposes a set of tools — actions like read a file, query an API, or update a record — that an MCP client can invoke while it works.
02
Open protocol
Built on the Model Context Protocol, so the same server works with any MCP client — Claude, Cursor, or your own app — without custom glue.
03
Resources & data
Beyond tools, a server can surface resources — files, records, documents — the AI can read into context on demand.
04
Connection & keys
Each listing shows the transport and any API keys or credentials the server needs, so setup is no surprise.

MCP servers vs skills, agents & assistants

An MCP server is one of several AI building blocks on Sigrix. Here is how it differs from the others:

Skill
A reference document a model reads. An MCP server is a live connector the model calls to act on real systems.
Agent
An autonomous tool that runs a task. An MCP server gives that agent the tools and data it acts on.
Assistant
A chat helper that can connect to MCP servers to reach your files, APIs, and apps.
MCP server
A Model Context Protocol connector that exposes tools, resources, and data for any MCP client to use.

An MCP server is a connector built on the open Model Context Protocol. It exposes a set of tools, resources, and prompts that an AI client like Claude or Cursor can call to act on real systems — files, APIs, databases, and apps.

The Model Context Protocol (MCP) is an open standard for connecting AI clients to external tools and data. A server speaks MCP, so any MCP-compatible client can discover and call its tools without custom integration code.

Yes. MCP servers on Sigrix follow the open protocol, so they work with any MCP client — Claude Desktop, Claude Code, Cursor, and others. Each listing shows the transport and any keys the server needs to connect.

Some MCP servers are free to claim and others are paid — each server's price is shown on its card and detail page. Either way you own an editable copy once you claim it.

Yes. Approved sellers can publish MCP servers on Sigrix: describe the tools and resources it exposes, document how to connect it, set a price, and list it. See the Sell page to get started.
