# Using the MCP Server

> Connect Reactive Resume to AI tools like Claude Desktop, Cursor, and Codex using the Model Context Protocol

The Reactive Resume MCP server lets you manage and modify your resumes through any MCP-compatible AI tool — Claude Desktop, Cursor, Codex, and more. It connects to the Reactive Resume API and exposes tools for listing, reading, and patching resumes using natural language.

## What is MCP?

The [Model Context Protocol (MCP)](https://modelcontextprotocol.io) is a standard that lets LLM-powered tools connect to external services. Instead of being limited to the built-in chat UI, you can use any MCP client to interact with your resumes.

## Prerequisites

<Steps>
  <Step title="Choose your authentication method">
    Reactive Resume MCP supports two authentication methods:

    * **OAuth2 (recommended):** best user experience for clients that support MCP OAuth.
    * **API key (fallback):** works in all clients that can send custom headers.

    Use OAuth2 whenever your MCP client supports it. Use API key only when OAuth is unavailable in that client.
  </Step>

  <Step title="If using API key, create one">
    Head over to [https://rxresu.me](https://rxresu.me) (or your self-hosted instance), sign in, and navigate to **Settings → API Keys**. Click **Create a new API key**, give it a name, and copy the secret — it's only shown once.

    For the full walkthrough, see [Using the API](/guides/using-the-api).
  </Step>
</Steps>

## Configuration

There are two transport options, and each can use either OAuth2 or API key depending on your client capabilities.

### Method 1: Streamable HTTP (recommended)

If your client supports the `url` field (e.g. **Cursor**, **Codex**, Claude custom connectors), use this.

#### Option A: OAuth2 (recommended)

Most OAuth-capable clients only need the MCP URL:

```json theme={null}
{
  "mcpServers": {
    "reactive-resume": {
      "url": "https://rxresu.me/mcp"
    }
  }
}
```

Then connect/sign in from the client UI (or with the client's OAuth login command).

#### Option B: API key (fallback)

If OAuth is not supported in your client, send `x-api-key`:

```json theme={null}
{
  "mcpServers": {
    "reactive-resume": {
      "url": "https://rxresu.me/mcp",
      "headers": {
        "x-api-key": "your-api-key"
      }
    }
  }
}
```

### Method 2: mcp-remote

If your client only supports `command` / `args` (for example, local-only Claude Desktop config), use [`mcp-remote`](https://www.npmjs.com/package/mcp-remote) as a bridge. This requires [Node.js](https://nodejs.org) **20 or later**.

`mcp-remote` is most commonly used with API keys:

```json theme={null}
{
  "mcpServers": {
    "reactive-resume": {
      "command": "npx",
      "args": ["mcp-remote", "https://rxresu.me/mcp", "--header", "x-api-key:your-api-key"]
    }
  }
}
```

<Info>Replace `your-api-key` with the API key you created in the prerequisites step.</Info>

### Where to put the config

| Client            | Config file                                                                                      |
| ----------------- | ------------------------------------------------------------------------------------------------ |
| Cursor            | `.cursor/mcp.json` in your project or home directory                                             |
| Claude Desktop    | `claude_desktop_config.json` ([docs](https://modelcontextprotocol.io/quickstart/user))           |
| Codex             | `~/.codex/config.toml` or `.codex/config.toml` ([docs](https://developers.openai.com/codex/mcp)) |
| Other MCP clients | Refer to the client's documentation                                                              |

## Authentication Details (How Reactive Resume MCP Works)

Reactive Resume MCP accepts authentication in this order:

1. **Bearer token (OAuth2 access token)** via `Authorization: Bearer <token>`
2. **API key fallback** via `x-api-key: <key>`

If neither is valid, the MCP endpoint responds with `401` and advertises OAuth metadata using:

* `WWW-Authenticate: Bearer resource_metadata="<instance>/.well-known/oauth-protected-resource"`

This lets OAuth-capable MCP clients discover and complete the OAuth flow automatically.

### OAuth2 flow used by this server

Reactive Resume is configured as an OAuth authorization server for MCP clients:

* The MCP endpoint is `https://rxresu.me/mcp`.
* OAuth discovery metadata is exposed under `/.well-known/*` endpoints.
* The login/authorization route is `/auth/oauth`.
* If the user is not signed in, `/auth/oauth` redirects to `/auth/login`, then resumes OAuth.
* If the user is signed in, `/auth/oauth` validates `client_id` and `redirect_uri`, issues an authorization code, and redirects back to the client.
* PKCE parameters (`code_challenge`, `code_challenge_method`) are preserved in the authorization flow.

## Popular Client Setup

### Cursor

**OAuth2 (recommended):**

```json theme={null}
{
  "mcpServers": {
    "reactive-resume": {
      "url": "https://rxresu.me/mcp"
    }
  }
}
```

**API key fallback:**

```json theme={null}
{
  "mcpServers": {
    "reactive-resume": {
      "url": "https://rxresu.me/mcp",
      "headers": {
        "x-api-key": "your-api-key"
      }
    }
  }
}
```

### Codex (CLI / IDE extension)

Add server:

```bash theme={null}
codex mcp add reactive-resume --url https://rxresu.me/mcp
```

Then log in with OAuth:

```bash theme={null}
codex mcp login reactive-resume
```

API key fallback (`config.toml`):

```toml theme={null}
[mcp_servers."reactive-resume"]
url = "https://rxresu.me/mcp"
http_headers = { "x-api-key" = "your-api-key" }
```

### Claude (web app custom connector)

Add `https://rxresu.me/mcp` as a custom remote MCP connector, then connect with OAuth in Claude's connector UI.

### Claude Desktop (local config file)

Use `mcp-remote` bridge with API key (example shown above in **Method 2**).

## Self-Hosting

If you're running a self-hosted Reactive Resume instance, replace `https://rxresu.me/mcp` with your instance URL:

```json theme={null}
{
  "url": "https://resume.example.com/mcp",
  "headers": {
    "x-api-key": "your-api-key"
  }
}
```

## Available Tools

Tool names use canonical unprefixed `snake_case` names.

| Tool                    | Description                                                                                                                        |

### Breaking change (tool names)

Older clients may refer to prefixed or dot-separated names. Those names are no longer registered; update automations and saved prompts to the canonical names above.

## Available Resources

Resources follow MCP conventions: **static** items appear in `resources/list`; **parameterized** access is declared in `resources/templates/list` and read via `resources/read` once you know the ID.

| Discovery                  | What you get                                                                                  |
| -------------------------- | --------------------------------------------------------------------------------------------- |
| `resources/list`           | Static resources only — currently **`resume://_meta/schema`** (ResumeData JSON Schema)        |
| `resources/templates/list` | **`resume://{id}`** — template for reading full resume JSON by ID (not enumerated per resume) |
| `list_resumes` (tool)      | **Primary way to discover resume IDs** — resumes are not listed as separate MCP resources     |

| URI                     | Description                                                             |
| ----------------------- | ----------------------------------------------------------------------- |
| `resume://_meta/schema` | ResumeData JSON Schema — use for valid JSON Patch paths and value types |
| `resume://{id}`         | Full resume data as JSON — use an ID from `list_resumes`                |

### Breaking change (schema URI)

The schema resource was previously `resume://schema`. It is now **`resume://_meta/schema`**. Update any saved prompts, automations, or client configs that referenced the old URI.

### Static server card (`/.well-known/mcp/server-card.json`)

`GET /.well-known/mcp/server-card.json` returns a JSON document ([SEP-1649](https://github.com/modelcontextprotocol/modelcontextprotocol/issues/1649)) with `serverInfo`, optional authentication metadata, and summaries of tools, resources, resource templates, and prompts. It is generated to match the live MCP server and can be used for discovery when a client cannot run a full capability scan against `/mcp/`.

## Available Prompts

Prompts are pre-built workflows that provide the AI with structured instructions and context. Each prompt embeds the resume data and the schema resource (`resume://_meta/schema`) automatically.

| Prompt           | Description                                                                                                                                                  |
| ---------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `build_resume`   | Guide you step-by-step through building a resume from scratch — basics, summary, experience, education, skills, and design                                   |
| `improve_resume` | Review your resume and suggest concrete improvements to wording, impact, metrics, and structure                                                              |
| `review_resume`  | Get a structured, professional critique with a scorecard (1–10 across seven dimensions) and prioritized recommendations. **Read-only** — no changes are made |

## Usage Examples

Once your MCP client is connected, you can use natural language to interact with your resumes:

### Browsing

* "List my resumes"
* "Show me my resume named 'Software Engineer'"
* "What skills are listed on my resume?"
* "Show me the stats for my resume"

### Creating & Managing

* "Create a new resume called 'Frontend Engineer 2026'"
* "Import this exported ResumeData JSON as a new resume"
* "What tags do I use across my resumes?"
* "Duplicate my 'Software Engineer' resume for a product manager role"
* "Make my resume public and give me the share link"
* "Lock my finalized resume so it can't be accidentally edited"
* "Delete my old draft resume"

### Editing

* "Update my name to Jane Doe"
* "Change my headline to Senior Software Engineer"
* "Add TypeScript to my skills with an Advanced proficiency level"
* "Add a new experience entry for my role as Staff Engineer at Acme Corp from Jan 2024 to Present"
* "Remove the third item from my skills section"

### Styling

* "Change the template to bronzor"
* "Set the primary color to blue"
* "Hide the interests section"

### Using Prompts

* "Help me build my resume from scratch" (uses `build_resume`)
* "Review my resume and give me a score" (uses `review_resume`)
* "Improve the wording on my resume" (uses `improve_resume`)

<Tip>
  The AI will use `read_resume` to inspect your current resume before making changes with `apply_resume_patch`. This
  ensures the correct JSON paths are used. Use `update_resume` for name, slug, tags, and public visibility (not for
  section content).
