# zkMCP
A Model Context Protocol (MCP) server for zero-knowledge proofs using circom. This repository provides tools for building circuits, performing trusted setup, generating proofs, and verifying proofs.
## Repository Structure
- `server/`: The MCP server implementation
- `examples/`: Example use cases for zero-knowledge proofs
- `age-verification/`: An example that demonstrates how to verify a person's age without revealing their birth date
## Installation
### Server Installation
1. Clone this repository:
```bash
git clone https://github.com/yourusername/zkMCP.git
cd zkMCP/server
```
2. Install dependencies:
```bash
npm install
```
3. Build the server:
```bash
npm run build
```
4. Add the server to your MCP settings configuration file:
```json
{
"mcpServers": {
"zkproof": {
"command": "node",
"args": ["/path/to/zkMCP/server/build/index.js"],
"env": {
"ZKINTRO_DIR": "/path/to/circom/projects"
},
"disabled": false,
"autoApprove": []
}
}
}
```
### Prerequisites
- Node.js (v14 or later)
- circom (v2.0.0 or later)
- snarkjs
## Usage
Once the server is installed and configured, you can use it to:
1. Build circuits from Circom files
2. Perform trusted setup for circuits
3. Generate proofs for circuits
4. Verify proofs
See the [server README](server/README.md) for detailed usage instructions.
## Examples
### Age Verification
The age verification example demonstrates how to use zero-knowledge proofs to verify that a person is above a certain age without revealing their actual birth date.
See the [age verification README](examples/age-verification/README.md) for more details.
