FlowLeap Patent AI: hosted MCP server

FlowLeap Patent AI is a hosted, remote Model Context Protocol (MCP) server for patent data. It gives your AI assistant read-only tools for EPO and USPTO records, patent searches, patent-law references and PATSTAT analytics.

https://api.flowleap.co/mcp

What it is


Server URL	`https://api.flowleap.co/mcp`
Transport	Streamable HTTP (remote; nothing to install)
Tools	51 tools, all read-only
Sign-in	OAuth 2.1 with a FlowLeap account, one scope: `patent-data`
Publisher	Flow Leap SASU
Registry name	`co.flowleap/flowleap`

The server also serves 6 MCP resources and 3 MCP prompts: the PATSTAT reference documents and three PATSTAT workflows.

What it does

Every tool reads data. No tool writes, files or changes anything at a patent office. The server's live tool list is the reference; the groups below are the tools at the time of writing.

How to connect

Add the server URL to your client. On first use, the client opens the FlowLeap sign-in page. Sign in with your FlowLeap account and allow the patent-data scope.

VS Code (GitHub Copilot)

Install in one click:

vscode:mcp/install?%7B%22name%22%3A%22flowleap%22%2C%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fapi.flowleap.co%2Fmcp%22%7D

Or add the server to your MCP configuration (.vscode/mcp.json uses servers):

{
  "servers": {
    "flowleap": { "type": "http", "url": "https://api.flowleap.co/mcp" }
  }
}

Cursor

Install in one click:

cursor://anysphere.cursor-deeplink/mcp/install?name=flowleap&config=eyJ1cmwiOiJodHRwczovL2FwaS5mbG93bGVhcC5jby9tY3AifQ==

Or add it to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "flowleap": { "url": "https://api.flowleap.co/mcp" }
  }
}

Claude Code

claude mcp add --transport http flowleap https://api.flowleap.co/mcp

Then run /mcp in Claude Code to sign in.

claude.ai, Claude Desktop and the Claude mobile apps

In Settings, open Connectors and add a custom connector.
Paste the server URL. No other field is needed.
Sign in to FlowLeap and allow the patent-data scope.

A connector you add on claude.ai belongs to your Claude account, so Claude Desktop and the Claude mobile apps show it too.

ChatGPT

In Settings, turn on developer mode.
Create a connector with the server URL and OAuth as its authentication.
Sign in to FlowLeap and allow the patent-data scope.

Gemini CLI

In ~/.gemini/settings.json:

{
  "mcpServers": {
    "flowleap": { "httpUrl": "https://api.flowleap.co/mcp" }
  }
}

Windsurf

In ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "flowleap": { "serverUrl": "https://api.flowleap.co/mcp" }
  }
}

Zed

In settings.json:

{
  "context_servers": {
    "flowleap": { "url": "https://api.flowleap.co/mcp" }
  }
}

If the agent lists only the authenticate tool after sign-in, ask it to authenticate once.

Amazon Q Developer CLI

In the agent configuration:

{
  "mcpServers": {
    "flowleap": { "type": "http", "url": "https://api.flowleap.co/mcp" }
  }
}

Then run /mcp in a chat to sign in in your browser.

Clients without OAuth: a personal token

A client that cannot sign in with OAuth can send a FlowLeap personal token as a bearer header. Make the token with the FlowLeap CLI (flowleap auth create-token). You can revoke it at any time. Replace fl_pat_... with your token.

Claude Code:

claude mcp add --transport http flowleap https://api.flowleap.co/mcp --header "Authorization: Bearer fl_pat_..."

Cursor and other clients with a url and headers entry:

{
  "mcpServers": {
    "flowleap": {
      "url": "https://api.flowleap.co/mcp",
      "headers": { "Authorization": "Bearer fl_pat_..." }
    }
  }
}

A personal token gives the same access as the OAuth sign-in.

Patent-Data Keys

The office tools (EPO OPS and USPTO ODP) read the patent office's data with a Patent-Data Key: an EPO OPS consumer key and secret, or a USPTO ODP API key. Each office gives these keys free of charge.

If your FlowLeap plan does not include FlowLeap's own office keys, the office tools use your own key.
Add your key once on the Patent-data keys page of your FlowLeap dashboard: https://www.flowleap.co/en/dashboard/keys. FlowLeap checks the key with the office, then keeps it encrypted. FlowLeap never shows the key value again.
Never type or paste a key in the chat. The assistant does not take a key in the chat. When a key is missing, the tool result names the keys page.
The PATSTAT tools need no Patent-Data Key.

Example prompts

"Show me Siemens' patent filings by year and office since 2016."
"Who dominates solid-state batteries?"
"Who cites EP3477840, and how?"
"Which CPC codes do perovskite tandem solar cell filings use?"
"How many of Siemens' EP patents were opposed, by year?"

Data and provenance

EPO OPS: live reads from the European Patent Office's Open Patent Services.
USPTO ODP: live reads from the USPTO Open Data Portal.
EPO PATSTAT Global: a self-hosted copy of the EPO's worldwide patent statistics database. Every PATSTAT answer names its data edition and carries the EPO attribution.
Read-only: every tool declares readOnlyHint: true. The server never writes to a patent office or to your data.
