# React Server Action Route Mapper MCP for AI Agents MCP

> React Server Action Route Mapper turns Next.js server actions into reliable API routes for your AI agent. It scans your code to find `use server` functions and generates consistent IDs so your agent doesn't guess wrong when trying to trigger backend logic.

## Description

If you have ever tried to get an AI agent to interact with a Next.js app, you know the frustration of watching it hallucinate random fetch URLs that don't exist. This MCP fixes that by creating a real map of your server actions. It looks through your JSX files, finds every function marked with the server directive, and assigns it a permanent ID using a bitwise hash. Instead of guessing, your agent uses these deterministic routes to trigger logic directly. You can even check if your code is valid before you run a scan or test how a specific name will look as a hash. It's part of the Vinkius catalog, making it easy to connect this mapping capability to any compatible client you're already using for development.

## Tools

### map_server_actions
Scans your JSX code to find and map all available server actions. It creates a reliable list of endpoints for your agent to use.

### preview_route_hash
Shows you exactly what the resulting hash will look like for a specific string. Use this to test name transformations before running a full scan.

### validate_component_syntax
Checks that your JSX is structurally correct before any scanning happens. This prevents errors caused by broken or malformed code snippets.

## Prompt Examples

**Prompt:** 
```
I have a new Next.js component with a deletePost action. What is its route ID?
```

**Response:** 
```
| Action Name | Route ID |
| :--- | :--- |
| `deletePost` | `d4e5f6g7` |
```

**Prompt:** 
```
Can you check if this JSX snippet is okay to scan? export async function save() { 'use server'; }
```

**Response:** 
```
The syntax is valid and ready for scanning. No structural errors were found in the component.
```

**Prompt:** 
```
What will the hash look like for a function named submitForm?
```

**Response:** 
```
The generated route ID for `submitForm` will be `a1b2c3d4`.
```

## Capabilities

### Generate deterministic route IDs
Creates permanent, hashed identifiers for your server functions.

### Scan JSX for server directives
Automatically finds all exported functions marked with use server.

### Verify component syntax
Checks your code structure to prevent mapping errors.

### Preview route transformations
Shows exactly how a function name will look as a hashed ID.

### Map Next.js actions to endpoints
Turns your existing application logic into an actionable map for agents.

## Use Cases

### Building an autonomous checkout agent
An engineer needs an agent to trigger a processPayment action. The MCP maps the function to a hash, so the agent calls the exact right route every time.

### Automating user profile updates
A developer uses the tool to expose updateProfile functions. Now their agent can modify user data via the generated deterministic routes.

### Testing Next.js API surface area
During a security audit, an engineer scans components to see which server actions are exposed and how they are mapped.

### Rapid prototyping of agentic features
A startup founder uses the MCP to quickly turn existing React logic into actionable tools for their new AI-powered app.

## Benefits

- Eliminate endpoint hallucination by providing your agent with deterministic route IDs via map_server_ handles.
- Ensure code reliability using validate_component_syntax to catch structural errors early.
- Predictable routing with bitwise hashing that you can test using preview_route_hash.
- Automate API discovery in Next.js apps without manual documentation updates.
- Keep your agent's connection to backend logic consistent even when files change.

## How It Works

The bottom line is you stop guessing endpoints and start using stable routes.

1. Point the MCP at your JSX or Next.js component files.
2. The tool scans for use server directives and extracts function names.
3. You get a reliable map of action names paired with their unique, permanent route hashes.

## Frequently Asked Questions

**How does React Server Action Route Mapper prevent agent errors?**
It provides your agent with a deterministic map of hashed routes. This ensures the agent calls the exact, correct endpoint every time instead of guessing.

**Can I use React Server Action Route Mapper for standard API routes?**
No, this tool is specifically designed to scan JSX and identify Next.js server actions marked with the use server directive.

**Does React Server Action Route Mapper work with any AI client?**
Yes, as long as your client supports the Model Context Protocol, you can use these mapped routes to trigger your backend logic.

**How do I know if my code is compatible with this MCP?**
You can use the syntax validation tool to check your JSX structure before attempting to map any server actions.

**Will React Server Action Route Mapper break if I rename my functions?**
The mapping uses a bitwise hash of the function name, so renaming a function will change its ID. However, it ensures the agent always has the most current, valid ID for the new name.
