How to Publish an MCP Server to the Marketplace

The BusinessMCP marketplace and registry are where MCP servers become discoverable. If you have built a server — whether it wraps an internal API, a database, or a public service — a listing gives it a home page, a canonical registry entry, and a distribution channel that AI-agent operators actually browse.

Discovery is the hard part of the MCP ecosystem. Anyone can write a server; far fewer people find it. A well-formed listing solves this by describing what your server does, which tools it exposes, and how to connect it, in a format both humans and agents can parse. The registry feed also syndicates your entry so it can surface in other MCP clients that read the standard.

For teams already hosting their unified business data on BusinessMCP, publishing is the natural next step: you expose a controlled, read-only slice of your platform as a public or partner-facing server and let external agents consume it safely.

Before you submit, make sure the server itself is solid. Every tool should have a clear name, a one-line description an LLM can reason about, and a well-typed input schema. Ambiguous tool names are the single biggest reason agents fail to use a server correctly, so spend time here — "search_orders_by_email" beats "query" every time.

Decide on your auth model. Public servers with no sensitive data can be open; anything touching real business data should require a Bearer token. BusinessMCP endpoints use mcph_ keys and enforce per-workspace isolation, so you can expose a specific dataset without risking the rest of your platform.

Write the human-facing copy as if a busy engineer will skim it in ten seconds. State the category, the headline capability, and one concrete example of a task the server enables. This copy becomes both your listing description and part of what search engines index for your page.

Head to the marketplace submit flow and fill in the listing form: name, slug, category, description, the connection URL or transport, and the list of tools your server exposes. The slug becomes your permanent URL, so choose something short and descriptive — it is a stable contract you will link to from docs and social.

Submissions go through a lightweight review to filter spam and broken endpoints before they appear publicly. Approved listings are served on the marketplace and pushed into the registry feed at the standard servers endpoint, so compatible clients can pull your entry programmatically.

Once approved, your server gets a dedicated page with its description, tool list, and install instructions. That page is indexable, so it doubles as an SEO asset — a genuine landing page for the problem your server solves.

A listing is not a launch. To get installs, treat the page like any other product: link to it from your README, your changelog, and your social posts, and make the value obvious in the first sentence. Servers that clearly state a job to be done — "turn your Stripe account into agent tools" — convert far better than vague technical descriptions.

Keep the listing fresh. Update the tool list when you add capabilities, fix the description as your positioning sharpens, and respond to the questions people ask. A stale listing with a broken endpoint gets quietly deprioritized; an accurate, active one earns trust.

Finally, close the loop with your own analytics. If you host your server on BusinessMCP, you can watch which tools agents actually call and which arguments they pass, then refine schemas and copy based on real usage rather than guesses.
