# HackerOne GraphQL MCP Server
A Docker image that provides access to HackerOne's GraphQL API through the Model Context Protocol (MCP).
**Supported MCP transport types**: Currently only stdio transport is supported. Please file an issue if you require [other transports](https://modelcontextprotocol.io/docs/concepts/transports#built-in-transport-types).
**Multi-Architecture Support**: This image supports both Intel/AMD (amd64) and Apple Silicon (arm64) architectures.
**Built on Apollo MCP Server**: This project is a thin wrapper around the upstream [Apollo MCP Server](https://github.com/apollographql/apollo-mcp-server), which exposes GraphQL operations as MCP tools.
## Quick Start
1. **Run with an MCP client**:
```sh
docker run -i --rm \
-e ENDPOINT="https://hackerone.com/graphql" \
-e TOKEN="" \
-e MUTATION_MODE="none" \
hackertwo/hackerone-graphql-mcp-server:1.0.7
```
## Docker Image Tags
- **`latest`**: Latest stable release (only updated on version releases)
- **`dev-main`**: Development builds from main branch
- **`1.x.x`**: Specific version releases
- **`pr-`**: Pull request builds
## Environment Variables
| Variable | Description | Default |
| ---------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------- |
| `ENDPOINT` | GraphQL endpoint URL | `https://hackerone.com/graphql` |
| `TOKEN` | Base64 encoded API token in format: `base64(username:api_key)` | - |
| `MUTATION_MODE` | Controls which mutations are allowed:
• `none`: No mutations allowed
• `explicit`: Only explicitly defined mutations allowed
• `all`: All mutations allowed | `none` |
| `DISABLE_TYPE_DESCRIPTION` | If set to `true`, tools will have no type descriptions (e.g. "The returned value has type ...") | `false` |
| `DISABLE_SCHEMA_DESCRIPTION` | If set to `true`, tools will have no schema description | `false` |
## Generating an API Token
### Option 1: Using the included script (recommended)
1. Visit https://hackerone.com/settings/api_token/edit to generate an API key
2. Run the token generation script: `./scripts/generate_token.sh`
This will prompt for your username and API key, then automatically encode and copy the token to your clipboard.
3. Use the resulting string as your TOKEN value
### Option 2: Manual encoding
1. Visit https://hackerone.com/settings/api_token/edit to generate an API key
2. Encode as: `echo -n "username:api_key" | base64`
3. Use the resulting string as your TOKEN value
## Example config in Flowise
1. Go to an Agent node
2. Go to tools
3. Select custom MCP
4. Put the following in the MCP parameters:
```json
{
"command": "/usr/local/bin/docker",
"args": [
"run",
"-i",
"--rm",
"-e",
"ENDPOINT=https://hackerone.com/graphql",
"-e",
"TOKEN=",
"-e",
"MUTATION_MODE=none",
"hackertwo/hackerone-graphql-mcp-server:1.0.7"
]
}
```
## Example config in editor (Zed)
```json
{
"context_servers": {
"hackerone-graphql-mcp-server": {
"source": "custom",
"command": "/usr/local/bin/docker",
"args": [
"run",
"-i",
"--rm",
"-e",
"ENDPOINT=https://hackerone.com/graphql",
"-e",
"TOKEN=",
"-e",
"MUTATION_MODE=none",
"hackertwo/hackerone-graphql-mcp-server:1.0.7"
]
}
}
}
```
## Notes
- The Docker container is designed to be piped into an MCP-compatible client
- Running the container directly will result in an error as it expects an MCP client connection
- The `-i` flag is required to maintain standard input for the stdio transport
- The `schema.graphql` in this repository may become outdated over time, you can download the latest one from HackerOne at [https://hackerone.com/schema.graphql](https://hackerone.com/schema.graphql)
## Development
### Creating a Release
To create a new release:
1. Create a [new release in GitHub](https://github.com/Hacker0x01/hackerone-graphql-mcp-server/releases/new).
2. GitHub Actions will automatically:
- Build multi-architecture images (amd64, arm64)
- Push to Docker Hub with appropriate tags
- Update the `latest` tag
### Manual Build (Local Development)
For local development and testing:
```sh
# Setup buildx
docker buildx create --name multiarch --driver docker-container --use
docker buildx inspect --bootstrap
# Build and push the image
bin/build
# Clean up
docker buildx rm multiarch
```
### Debugging
1. **Run MCP inspector:**
```sh
npx @modelcontextprotocol/inspector
```
3. **Connect to the HackerOne MCP server from the web interface:**
Command:
```sh
/usr/local/bin/docker
```
Arguments:
```sh
run -i --rm -e ENDPOINT=http://host.docker.internal:3000/graphql -e TOKEN= -e ALLOW_MUTATIONS=all hackertwo/hackerone-graphql-mcp-server:1.0.5
```
## Issues & Contributions
- **HackerOne-specific behavior, configuration, token handling, schema quirks, mutation allow-listing, etc.:** open an issue in this repository.
- **Generic MCP behavior, transports, protocol details, or GraphQL tool exposure mechanics:** consider checking/filing upstream in **apollographql/apollo-mcp-server**.
