Create an API key and give it a cap. Paste the message into a new Muse chat, as it is and in English: the setup line tells Muse how to talk to the server. Muse answers with a Metix connector card. Click Connect, accept Meta's notice about custom connectors, and type the key into the API key field. Never paste the key into the chat, which Muse keeps.
Add my Metix connector:
https://mira-api.metix.ai/mcp
- Setup: standard MCP over streamable HTTP. Every request needs the header Authorization: Bearer <my Metix key>. Ask me for the key through your secure credential prompt; never ask for it in chat and never print it. Send Accept: application/json, text/event-stream on every request. Keep the Mcp-Session-Id returned by initialize and send it on every later call.
- Skill: save one so any question about people, job postings or companies goes through Metix tools first. Call metix_get_contract before the first search and follow it if it disagrees with this note. Searches return ids; read records with the matching get tool, at most 100 ids per call. Keep size at 5 or less unless I ask for more.
Once you are in, list the tool names you got, call metix_get_key_status, then answer this with them:
find three open machine learning engineer postings in San Francisco and tell me the company and the posted salary range for each.Then
Muse then asks once whether it may share information with mira-api.metix.ai. Choose Always allow this site, or every new chat asks again. It lists the ten Metix tools, checks your key and answers the question at the end of the message, in about two minutes. It also saves a skill, so in any later chat you just ask. When a question could also be answered from the web, such as a company before an interview, start it with "Use Metix:" or Muse may search the web instead.
Ask it first
Find five senior data engineers in Austin who have worked at a fintech company. Give the name, current title and current company, and how many API Credits it cost.Meta's terminal coding agent reads servers from the mcp_servers block of its settings.json and expands ${METIX_KEY} from your environment.
{
"mcp_servers": {
"metix": {
"transport": "streamable_http",
"url": "https://mira-api.metix.ai/mcp",
"headers": { "Authorization": "Bearer ${METIX_KEY}" }
}
}
}Then
/mcp inside Muse Code lists the connected servers. The agent skills need no extra step: Muse Code already reads ~/.agents/skills.
Things to ask in Muse
Once it is connected, ask the way you would ask a colleague. Four of these are real runs in Muse, redrawn with personal details removed; the other two are samples. The conversation is the same on the Mac app, muse.ai and your phone. If a question could be answered from the web, start it with “Use Metix:” so Muse reads the data instead of searching.

Real runs were made against live data, so their postings and counts will have changed by the time you read this. Samples describe roles without naming real people, and the balance in the key example is made up. The character is our Muse companion in the Metix AI hoodie. Muse is a trademark of Meta Platforms.
Questions
Is this a Meta-reviewed connector?
No. It is a Muse custom connector: you describe a server to Muse in one message and it connects on its own. Meta does not review custom connectors, which is why everything it can and cannot do is written on this page.
Muse added facts that are not in Metix. Why?
Muse is a general agent and may fill a gap from the web, for example a company's founded year when the Metix record leaves it blank. It usually says so. If you need to know where each fact came from, ask: "Say which facts came from Metix."
How do I disconnect it?
In Muse's settings, under connectors, remove Metix. To stop it everywhere at once, revoke the key on the API keys page; it stops working on the next call.
Does Muse see my key?
Muse keeps credentials in its secure store and, by Meta's account, uses them without seeing them. Our servers see the key only in the Authorization header of each request, as with any MCP client.
What does it cost?
The same as any other use of the API. A search costs one API Credit per 25 results and reading records costs one per 5; natural-language search adds a 5 API Credit base. The free plan includes 100 API Credits once, with no card.
Can I limit what an agent spends?
Yes. On the API keys page, give the key the agent uses a cap in API Credits. Many agents call tools without asking you each time, and a capped key stops at the cap. Revoking a key stops it on the next call.
Why did one question cost hundreds of API Credits?
Questions that rank or count across everything, such as "which companies posted the most data engineer roles", have no single call that answers them, so an agent may read every match to count it. In one test, Grok Build pulled all 8,799 matching postings for that question and used about 390 API Credits. Ask for a handful instead ("five recent data engineer postings"), keep a cap on the key, and ask the agent to tell you before a call returns more than 100 results.
Can it find email addresses or phone numbers?
Yes, for any account that has paid, a plan or a top-up, billed per value found: 3 API Credits for a work email, 8 for a personal email, 15 for a phone. Unlock is a REST call, not an MCP tool, so install the skills and the agent makes the call for you. The Platform does not send outreach or book interviews; for that, use Mira at metix.ai.
Mira Credits or API Credits?
API Credits. They are the Metix AI Platform's usage unit. Mira Credits, sold with hiring plans on metix.ai, are a different unit, and the two are not interchangeable.
