Endpoint

Streamable HTTP MCP.

https://missingmanual.ai/mcp

Do not fetch that URL as a document. It is an MCP transport, not a page.

Claude Code

One command.

claude mcp add --transport http missing-manual https://missingmanual.ai/mcp

Cursor and other clients

One config entry.

Clients that keep an mcpServers map — Cursor in ~/.cursor/mcp.json, among others — take the endpoint directly.

{
  "mcpServers": {
    "missing-manual": {
      "url": "https://missingmanual.ai/mcp"
    }
  }
}

Optional agent skill

The safe sequence, in one file.

Compatible agents can use the MissingManual client skill for the create, capability, polling, and receipt sequence. The skill adds no service dependency; the MCP tool descriptions remain sufficient on their own.

What the agent sends

A maximum, and a way to pay it.

create_guide takes a topic, an idempotencyKey, and maxTotalChargeUsdMicros — the ceiling your agent authorizes, in USD micros, as a whole number of cents. The payment credential travels in MCP protocol metadata, not as a model-visible tool argument.

The server publishes the minimum authorization it will accept. A request below that minimum is refused rather than started at a price that cannot cover the run.

The call returns a job id and one opaque capability. Keep both. They are the only way to read the guide, and they are not recoverable.

Then

Poll, and read the receipt.

get_guide takes that job id and capability. While the run is in flight it returns status and a suggested poll delay. Reads are free. After the run finishes and the charge settles, the same call returns the markdown and an itemized receipt.

A failed or cancelled run returns no markdown and charges $0.

Check the origin

Health.

curl -s https://missingmanual.ai/healthz

This reports whether the service is up and whether it is currently accepting paid runs. It starts nothing and costs nothing.
