PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Search & AI memory

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • Can do 5 things (tools) cobaltintelligence_list_states, cobaltintelligence_search_businesses, cobaltintelligence_get_business, cobaltintelligence_get_business_by_sos_id …
  • The registry lists no key to fill in.

  • cobaltintelligence_get_business_by_sos_id

    Get the Secretary of State record for one filing id (SOS id) in one state. Use the id from cobaltintelligence_search_businesses or a previous record. A slow search returns a retryId. Cobalt API: GET /v1/search?sosId=. Entity records only. Not a consumer report under the FCRA. Do

  • cobaltintelligence_get_search_result

    Check a search that returned a retryId. Makes one call and does not wait. Call again later if the status is still Incomplete. Cobalt API: GET /v1/search?retryId=. Entity records only. Not a consumer report under the FCRA. Do not use it to screen, score or decide on any person's e

Common questions

Is Cobalt Intelligence MCP by usefulapi safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Context7, Codebase Memory, Exa

Cobalt Intelligence MCP by usefulapi

Use your Cobalt Intelligence account from Claude, Cursor, or any MCP client. Search US state business-entity records and read Secretary of State filings. Hosted, no local install: connect with your own credentials.

Live endpoint: https://cobalt-intelligence.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://cobalt-intelligence.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http cobalt-intelligence https://cobalt-intelligence.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
{

"mcpServers": { "cobalt-intelligence": { "url": "https://cobalt-intelligence.usefulapi.io/mcp" } } }

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Cobalt Intelligence credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/cobalt-intelligence/

On first connect you provide a Cobalt Intelligence API key (the x-api-key value from your Cobalt Intelligence account). The server validates it and stores it per user. No keys go in config files.
