Discovery

In the ChatGPT Apps Store.
In Claude Connectors. From one build.

Shipping is not the same as being found. Your server shows up as an entry people can browse and install, in the connector directory of a chat client and in the app store next to it, with the icon, copy and screenshots already filled in.

What you skip

Why teams pick Mcpfy

Seven jobs stand between a working tool and something people can install. You can write all of them, or none of them.

By hand

With mcpfy

Hosting

Pick a host, write a Dockerfile, wire up TLS and a domain.

Connect the repository. Every push ships.

Preview environments

Stand up a second stack, or test in production and hope.

A live MCP URL for every branch, automatically.

Secrets

A .env file, a secret manager, and a way to keep them in sync.

Per-environment variables injected at runtime.

Debugging

console.log, then redeploy, then read the logs again.

Every JSON-RPC frame captured, with session replay.

Testing across clients

Open ChatGPT, then Claude, then Cursor, and click through each one.

One suite, run across clients and models, judged automatically.

Analytics

Bolt on a generic APM that has never heard of a tool call.

MCP-native volume, latency, errors and per-tool health.

Getting listed

Read the directory guidelines and assemble the pack by hand.

Publish checks, then a generated submission pack.

What people say

Priya Raman@priyabuilds

Been meaning to try mcpfy. Started a ChatGPT app today and wasn't sure it was the right use case. Turns out it very much is.

Marcus Oyelaran@moyelaran

Easily the smoothest Python path for building an agent-facing MCP server. I can iterate from the CLI and test against a real agent in seconds. Most tooling assumes you're only ever in a chat client.

Ines Ferreira@inesferreira

Widget support landing on the open spec matters: the whole community benefits when compatibility is the default instead of an afterthought.

Philipp Braun@pbraun

Great to see mcpfy shipping in the open. We're running a hack night with them next week to put it through its paces 😉

Victor Tran@vtran

Sharp execution. They've stripped deployment and aggregation down to one endpoint. Data teams and internal dashboards could slot this in and cut weeks off agent builds.

Tomas Lindqvist@tlindqvist

Solid addition to the MCP client ecosystem. The Inspector alone saved me an afternoon.

Elena Sokolova@esokolova

The open way to connect any model to any MCP server and build agents with real tool access, without getting locked into one vendor's client.

Darren Cole@dcole

mcpfy is really onto something here.

Jeffrey Nwosu@jeffnwosu

MCP evals are finally a first-class thing and not a pile of bash scripts I maintain alone 👀

Aisha Mahmood@aishamah

Just found this: an open library that connects any LLM to MCP tools for custom agents, with browsing, search and file access working out of the box.

Infra isn't just plumbing, it's distribution. Whoever owns the rails agents use to talk to the outside world ends up with real leverage.

Reuben Adeyemi@reubendev

Shipped our internal MCP server to production before standup finished. git push, done. 🚀

Hana Kobayashi@hanakb

Open-source dev tools and infrastructure for MCP, helping teams build and deploy custom agents fast. Exactly the layer that was missing.

Clara Bennett@clarabee

Launched! Open infrastructure for MCP agents: spin up and aggregate servers behind a single endpoint with zero friction.

Pietro Zullo@pzullo

Code mode in the client is a great call. Define which servers the agent can use, flip it on, and the agent discovers tools and executes against them as plain modules.
