FastMCP Authority

Everything we learned building 70% of MCP servers — yours by default.

FastMCP is the open-source Python framework behind 70% of MCP servers worldwide, with 78.7M+ downloads last month. Every pattern we discovered, every failure mode we fixed — it's baked into the Horizon platform.

Horizon is where those servers run in production. If you are already using FastMCP, deploying to Horizon is one git push. If you are using another framework, Horizon works with any spec-compliant MCP server.

FastMCP to Horizon

From FastMCP code to a live MCP server URL.

Write your server in Python, push to GitHub, and get a production MCP server URL in 60 seconds. Horizon adds OAuth 2.1, dynamic client registration, scaling, and monitoring without extra deployment scripts.

View FastMCP documentation
from fastmcp import FastMCP
mcp = FastMCP("my-tools")
@mcp.tool()
def query_database(sql: str) -> dict:
    return db.execute(sql)
# Deploy to Horizon
$ git push origin main
# Live at https://my-tools.horizon.prefect.io in 60 seconds

Managing MCP servers at scale is the real challenge.

One MCP server is easy. Fifty servers across 5,000 employees, each needing authentication, access control, and monitoring, is the problem Horizon solves.

Where are your MCP servers deployed?
Horizon Deploy gives every server a managed production URL with OAuth 2.1. No infrastructure to manage.
Which MCP servers exist across your org?
Horizon Registry catalogs every internal and third-party MCP server with ownership, versioning, and approval status.
Who can access which MCP tools?
Horizon Gateway enforces tool-level RBAC, authentication, and audit logging across every server.

The Platform

Ship MCP servers in seconds. Govern them for the enterprise.

Customer Proof

Teams are already running MCP in production with Horizon.

Theory Venturescase-study

Because we've built these bespoke MCP tools with Horizon, I can stay in my LLM chat UI for a lot longer and get the information I need directly without having to tab through all these different places to copy and paste.

Horizon actually had the best onboarding experience on my team. Even people who have not done tech before were able to onboard onto the tool, which is a very strong sign of ease of use.

Horizon is the avenue by which we can best deploy MCP within our organization. Out of the box, take my GitHub repo, launch it, and it just works for us.

Protocol-Native

One endpoint. Every AI client.

Horizon MCP servers work with any client that supports the Model Context Protocol. Deploy once, then connect from Claude, Cursor, Windsurf, VS Code, OpenAI, Bedrock, and more.

Claude

Add Horizon servers as custom Connectors in Claude for Work.

Cursor

Connect to Horizon MCP servers from Cursor's AI coding environment.

Windsurf

Use Horizon servers with Windsurf's agentic IDE.

VS Code

Connect GitHub Copilot and other VS Code MCP clients to Horizon servers.

Amazon Bedrock

Integrate Horizon MCP servers with Bedrock agents and internal tools.

OpenAI Agents

Use Horizon servers with OpenAI's agent framework and MCP-compatible tooling.

Any MCP client

Horizon speaks the MCP spec, so any compliant client works.

Claude Connectors

Claude Connectors powered by Horizon.

Anthropic's Claude for Work lets teams add custom Connectors by pasting in a remote MCP server URL. Horizon Deploy gives you that URL, with OAuth 2.1 and enterprise access controls already handled.

Deploy MCP Servers

Deploy MCP servers with one git push.

Connect your repo and Horizon builds, containerizes, and deploys your MCP server to a production URL — with OAuth 2.1 auth, autoscaling, and observability configured automatically.

Differentiation

The MCP platform built by the team that built the ecosystem.

No other MCP platform combines open-source framework leadership with full-lifecycle enterprise infrastructure.

Built by the creators of FastMCP

We created the framework behind 70% of MCP servers — we know what breaks at scale.

Full lifecycle, not just one piece

Deploy, catalog, secure, and monitor MCP servers in one platform instead of stitching together point solutions.

Production-grade from day one

OAuth 2.1, RBAC, audit logs, auto-scaling, and monitoring are built in for real production workloads.

Works with the AI clients teams actually use

Any MCP client. Any MCP framework. Claude, Cursor, Windsurf, VS Code, OpenAI, and Bedrock.

Quick Start

Go from code to production in three steps.

Horizon keeps the path from MCP code to a governed production endpoint short enough for individual developers and robust enough for enterprise teams.

01

Write your MCP server

Use FastMCP or any MCP framework to define the tools your agents need.

02

Push to GitHub

Connect your repo to Horizon. Every push to main auto-deploys and pull requests get preview environments.

03

Share the URL

Your server gets a production URL with OAuth 2.1, ready for Claude, Cursor, Windsurf, OpenAI, or any MCP client.

Deploy your first MCP server in 60 seconds.

Free for personal projects. Enterprise governance and RBAC for teams. No credit card required.
