# Install MissingManual

One remote endpoint, added once. There is no package to install, no key to
issue, and no account to create.

## Endpoint

```
https://missingmanual.ai/mcp
```

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

## Claude Code

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

## Cursor and other clients

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

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

## Optional agent skill

Compatible agents can use the
[MissingManual client skill](/skills/missing-manual-client/SKILL.md) for the
safe 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

`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

`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

```
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.
