Works today

Anthropic documentation

Register the server once, for your user rather than one project, so it is there in every repository you open.

Terminal
claude mcp add --scope user --transport http metix \
  https://mira-api.metix.ai/mcp \
  --header "Authorization: Bearer $METIX_KEY"

Then

Run claude mcp list and look for metix marked Connected. You never name the tools: ask for what you want and Claude picks them.

Anthropic documentation

The Messages API connects to the server itself when you pass it in mcp_servers, so your code never handles the tool calls.

Request
curl https://api.anthropic.com/v1/messages \
  -H "x-api-key: $ANTHROPIC_API_KEY" \
  -H "anthropic-version: 2023-06-01" \

Then

The response carries the tool calls and results as content blocks, followed by Claude's answer.

In the apps

These apps add tools through their own connector settings. The quickest start is the tool beside each, which takes your key directly.

Questions

Can I add it to Claude.ai or Claude Desktop?

Yes. Claude.ai adds custom connectors in its own settings, and organizations with request-header connectors can add the Metix key there. The quickest start is Claude Code or the Claude API, which take your key directly.

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.
