### Description (declared)

# modal-mcp

A read-only MCP server that exposes [Modal](https://modal.com) to LLM agents for
debugging and observing deployed applications: logs, app and function state, container
lifecycle, failures, deployment history, and cost.

**Read-only by construction, permanently.** No tool in this server can create, change,
stop, restart or delete anything in a Modal workspace. That is not a flag, a toolset
toggle, or a refusal at the edge — the mutating RPCs are unreachable as attributes on the
object the tool layer holds. See [The read-only boundary](#the-read-only-boundary).

Status: **alpha.** Every tool has been exercised against a real Modal workspace; the
gaps are listed honestly in [What this cannot see](#what-this-cannot-see).

Published to PyPI as **`modal-mcp-op`**. The obvious name `modal-mcp` was already
taken by an unrelated project with similar positioning.

## Install and run

```bash
uvx modal-mcp-op stdio                # or: uv tool install modal-mcp-op
export MODAL_TOKEN_ID=...
export MODAL_TOKEN_SECRET=...
modal-observe stdio
```

Credentials come from the **process environment only**. The server does not read a `.env`
file; `.env.example` is a template you source yourself:

```bash
cp .env.example .env && set -a && . .env && set +a
```

There is no interactive login, no linked-project state, and no config file — so this runs
headless in a container or a CI job.

MCP client configuration:

```json
{
  "mcpServers": {
    "modal": {
      "command": "modal-observe",
      "args": ["stdio"],
      "env": { "MODAL_TOKEN_ID": "...", "MODAL_TOKEN_SECRET": "..." }
    }
  }
}
```

**Use a service-user token with a Viewer role** rather than a personal user token. This
server only ever reads, so it needs nothing more, and a user token inherits a human's
full workspace access. `modal_status` reports which kind it holds so a mismatch is
visible.

## Driving it without an MCP client

Everything is reachable from a shell, because that is the only way to debug it…
