## Introduction

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including Mintlify.
This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Mintlify account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions.

## TL;DR

### How Atomic Agent connects to Mintlify
Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.
Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

## Connect Mintlify MCP to Atomic Agent

### Connect Mintlify to Atomic Agent
- Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key.
- In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
- Ask Atomic Agent to do something in Mintlify. It searches Composio for the right tool.
- On first use, open the sign-in link returned in the chat. Connect your Mintlify account, then return to Atomic Agent to continue.
### Headless setup
Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

```bash
COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY
```

## What is the Mintlify MCP server, and what's possible with it?

The Mintlify MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Mintlify account. It provides structured and secure access so your agent can perform Mintlify operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `MINTLIFY_MCP_CHECKOUT` | Checkout | Select a deployment and open its editor session in one call. This is an org-wide connection, so `subdomain` is required to choose which deployment to open. Subsequent editor tools act on the active session. Required before editor branch tools; deployment-level operations (workflows, deployment, members, billing, integrations, analytics) are reached via `execute_code` and do not require checkout. Calling checkout on another subdomain switches the active session without losing the others; re-checking-out an already-open deployment just re-activates it. Pass `branch` to work on a specific branch — if it already exists in git, the session attaches to it as-is; if not, it is created from `from` (defaults to the deploy branch). Omit `branch` to auto-generate a fresh `admin-mcp/-` branch from `from` (uses `slug` when provided, otherwise the session id); if that branch already exists (e.g. a retried task) the session resumes it. Returns `{ branchName, sessionId, baseBranch, baseSha, created, note?, editorUrl, toolkit }`. `toolkit` groups the tools you should load next (`explore`, `editContent`, `editNavigation`, `editConfig`, `codemode`, `ship`) so you can call them without further discovery. Surface `editorUrl` to the user so they can follow along in the dashboard editor as the agent works. |
| `MINTLIFY_MCP_CREATE_NODE` | Create node | Insert a node into the navigation tree under `parentId` (null = root). `order` is clamped into siblings and defaults to append. `data` is discriminated by `type`: `page` seeds a Y.Doc from `{ path, content }` (MDX is validated), while `group`, `tab`, `anchor`, `version`, `language`, and `product` take their own name-shaped fields. Parent/child compatibility is enforced against an allowed-children table (e.g. groups cannot contain tabs; pages have no children). |
| `MINTLIFY_MCP_DELETE_NODE` | Delete node | Remove a node and its subtree from the navigation tree by `nodeId`. For pages in the removed set, the hocuspocus room, document S3 blob, and baseline (Redis + S3) are cleaned up. To add a redirect for a removed page, use `update_config` with `add_redirect`. Returns `{ deletedNodeIds }`. |
| `MINTLIFY_MCP_DIFF` | Diff | Returns the list of changes between current session and main. |
| `MINTLIFY_MCP_DISCARD_SESSION` | Discard session | End the session without creating a PR |
| `MINTLIFY_MCP_EDIT_PAGE` | Edit page | String-replace edit on a page Y.Doc body. Use this for MDX content edits only — do NOT use it to change frontmatter fields (`title`, `sidebarTitle`, `description`, `icon`, `tag`, `canonical`, `og:*`, `keywords`, `noindex`, `hidden`, etc.); those round-trip through structured node metadata and must be set via `update_node` with `data.type='page'`. For the site-level `description` in `docs.json`, use `update_config`. Edits are broadcast live to connected collaborators: plain inline-text edits inside a single paragraph stream character-by-character (typing effect); structural edits apply atomically. The returned `mode` reports which path ran (`inline-stream` or `rebuild`). |
| `MINTLIFY_MCP_EXECUTE_CODE` | Execute code | Run TypeScript/JavaScript against the Admin MCP dashboard SDK inside a sandboxed Cloudflare isolate. The script body has access to top-level namespace proxies (workflows, deployment, members, billing, integrations, analytics, deployments) plus console. No outbound fetch, no bindings, no secrets. The OAuth scopes on the calling token gate each individual SDK call through the gateway. **Targeting deployments**: every namespace method takes an optional second argument `{ subdomain }` to target a specific deployment in the org — e.g. `workflows.listWorkflows({}, { subdomain: 'acme' })`; omit it to use the token's default deployment. You can target different deployments in a single run. `deployments.list()` enumerates the org's deployments (org-wide; requires the `deployment:read` scope) and returns `{ deployments: [{ _id, subdomain }, ...] }`. **Return semantics**: the script is wrapped in an async function and the value of the LAST expression statement becomes the result — `await workflows.listWorkflows();` on its own line works, but a bare `return X;` at top level is dropped (no enclosing function), and `export default async function() { return X; }` returns the function object, not `X`. To return a structured value either end with an expression (`({ a, b });` or just `x`) or assign to a variable and reference it on the last line. Returns a tagged-union envelope: { ok: true, result, logs, truncated, durationMs } \| { ok: false, error: { code, message }, logs, truncated, durationMs }. `truncated: true` signals the result or logs hit the size cap. Error codes: unauthorized, invalid_json, invalid_request, misconfigured, timeout (30s wall-clock), sandbox_error (anything thrown inside the script), execution_failed (worker plumbing failure). |
| `MINTLIFY_MCP_GET_SESSION_STATE` | Get session state | Get current session state including branch name, edited files, and nav diff |
| `MINTLIFY_MCP_LIST_BRANCHES` | List branches | List all git branches available for a deployment before or after checkout. Pass `subdomain` to target a deployment; it defaults to the active session and is required before checkout on this org-wide connection. Optionally filter with `query` to only return matching branch names. Returns `{ branches, total, deployBranch }`. |
| `MINTLIFY_MCP_LIST_DEPLOYMENTS` | List deployments | List the deployments this connection is authorized for, returning each `{ subdomain, name }`. On an org-wide connection this is every main (non-preview) deployment in your organization; on a connection scoped to specific deployments it returns only those. Use this to discover which subdomain to `checkout` before editing. Hidden when the connection is pinned to a single deployment. |
| `MINTLIFY_MCP_LIST_NODES` | List nodes | List navigation nodes with optional filters over the current branch nav tree. `parentId: null` returns root-level nodes; a string returns direct children of that node; omit for no filter. `recursive: true` extends the parent filter to all descendants of `parentId` — pair with `parentId: null` (or omit) to dump the entire tree in a single call. `type` accepts a single type or array (e.g. "group"). `language`, `version`, and `tab` are scope filters: a node passes only if its ancestor chain (including itself) contains a matching division node — filtering by a value not present in the tree returns empty. `limit` defaults to 500 (max 500). `cursor` is an opaque pagination token returned as `nextCursor`, stable across inserts. Returns { nodes, nextCursor } where nextCursor is null when exhausted. |
| `MINTLIFY_MCP_MOVE_NODE` | Move node | Reposition a node in the navigation tree by nodeId. `parentId: null` moves to root; omit to keep the current parent. `order` is 0-based among the new siblings; omit to append. At least one of `parentId` or `order` is required. Parent/child compatibility is enforced against the allowed-children table. Cross-boundary moves (across version, tab, language, or product ancestors) are allowed; the response flags them via `crossedBoundary`. |
| `MINTLIFY_MCP_READ` | Read | Read the full MDX content of a single page on the current branch. Reflects in-session edits made via edit_page/write_page, not just the published version. `path` is the page href (e.g. "/quickstart" or "guides/setup"), with or without a leading slash or trailing .mdx. Returns `{ content, filePath }` on success, or `{ error: "read_failed", reason }` on failure (`reason` carries the human-readable diagnostic such as "No valid pageId found for page" or a hocuspocus connection error). |
| `MINTLIFY_MCP_SAVE` | Save | Flush branch to git. With mode="auto" (default) opens a PR if none exists, otherwise commits to the existing PR branch; it only auto-merges when this deployment's agent review setting is push-to-main. With mode="pr" opens a PR if none exists, otherwise commits to the existing PR branch, and never auto-merges. With mode="commit" commits directly to the branch without opening a PR. |
| `MINTLIFY_MCP_SEARCH` | Search | Find lines matching a substring or regex across every page on the current branch. Returns { matches, truncated } where each match is { path, lineNumber, line }, sorted by path. Reflects in-session edits: pages edited in this session are scanned even before indexing catches up. `query` is treated as a literal fixed string by default; pass `regex: true` for regex syntax. `caseSensitive` defaults to false. `limit` caps results (default 100, max 500). The response is bounded to 30KB — `truncated: true` indicates results were dropped and you should refine the query. |
| `MINTLIFY_MCP_SEARCH_CODE_OPERATIONS` | Search code operations | Lexical (BM25) search over the Admin MCP code-mode SDK. Use this to find the right SDK method for a task before writing an `execute_code` script. `query` is matched against method names, namespaces, parameter names, and JSDoc descriptions (camelCase tokens like `createWorkflow` are split, so `create workflow` also matches). Pass `namespace` (one of workflows, deployment, members, billing, integrations, analytics) to scope results to a single namespace — this also enumerates that namespace (every method in it, best query matches first), e.g. to confirm whether a getter exists. Returns up to `limit` hits (default 5, max 20), each `{ operationId, namespace, method, requiredScope, description, inputSchema, score }`. `inputSchema` is the full JSON Schema for the method’s parameters — no extra lookup needed before calling `execute_code`. Returns `{ hits: [] }` when nothing matches. |
| `MINTLIFY_MCP_UPDATE_CONFIG` | Update config | Update any top-level `docs.json` field except `navigation` (use the navigation tree tools for that). This is the ONLY way to change the site-level `description` (the SEO/social description for the whole docs site) — do not use `edit_page` (which targets page body) or `update_node` (which targets a single page's frontmatter description). `op` selects the operation: `set` ({ docsConfig }) shallow-merges any partial `docs.json` (e.g. `{ theme, name, description, colors, logo, favicon, api, appearance, background, navbar, footer, fonts, search, contextual, banner, interaction, errors, seo, styling, integrations, metadata, ... }` — see https://www.mintlify.com/docs.json); `add_redirect` ({ redirect: { source, destination, permanent? } }) appends to `redirects` (rejects on duplicate source); `remove_redirect` ({ source }) removes by source (rejects if missing). `set` rejects `navigation` and `$schema` keys. Set a top-level key to `null` in `docsConfig` to unset (remove) it entirely. The merged config is validated against the @mintlify/validation schema — any violation rejects the call with no partial writes. Returns `{ diff }` of only the changed fields: array-valued fields (e.g. `redirects`, `navbar.links`) report `{ added, removed }`, nested objects recurse under `{ changed }`, and scalar leaves report `{ before, after }`. |
| `MINTLIFY_MCP_UPDATE_NODE` | Update node | Update a navigation node's properties in place by nodeId — no repositioning. `data` is a discriminated union on `type` carrying partial, type-specific fields that are merged into existing `node.data`. For `type:'page'`, this is the correct tool for editing the page's frontmatter (`title`, `sidebarTitle`, `description`, `icon`, `tag`, `canonical`, `og:title`, `og:url`, `keywords`, `noindex`, `hidden`, `deprecated`, etc.) — the merged fields are serialized back into the MDX `---` block on save; do not use `edit_page` for these. `data.type` must match the stored node type. Immutable fields (`href`/`pageId` on pages, internal flags) are rejected — use `move_node` to rename a page path. Page updates emit an `update` pending action with source `metadata`; structural node updates emit an `update-navigation` action. Emits `editor_nav_updated`. Examples: set a page's frontmatter description (`{type:'page', description:'…'}`), rename a group (`{type:'group', group:'New Name'}`), change a tab icon, set a version as default. |
| `MINTLIFY_MCP_WRITE_PAGE` | Write page | Full overwrite of a page Y.Doc content |

## Troubleshooting

### Why is my API key rejected?

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying.

### Why are Composio tools unavailable after saving a key?

Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk.

### Does Composio have a free plan?

The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection.

## Complete Code

None listed.

## Conclusion

### Use Mintlify from Atomic Agent
With your account connected, ask Atomic Agent to work with Mintlify in natural language. You can connect more apps through the same Composio integration as you need them.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Mintlify MCP?

With a standalone Mintlify MCP server, the agents and LLMs can only access a fixed set of Mintlify tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Mintlify and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Atomic Agent?

Yes, you can. Atomic Agent fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Mintlify tools.

### Can I manage the permissions and scopes for Mintlify while using Tool Router?

Yes, absolutely. You can configure which Mintlify scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Mintlify data and credentials are handled as safely as possible.
