If you already use Mcpizer, the mcpizer mcp server is the piece that lets your assistant work with it directly. MCPizer lets your AI assistant (Claude, VS Code, etc.) call any REST API or gRPC service by automatically converting their schemas into MCP (Model Context Protocol) tools.
MCPizer is a server that: - Auto-discovers API schemas from your services (OpenAPI/Swagger, gRPC reflection, .proto files) - Converts them into tools your AI can use - Handles all the API calls with proper types and error handling
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
github — //myorg/api-specs/main/user-api.yaml # Uses gh CLI authgrpc — //my-grpc-service:50051url — https://raw.githubusercontent.com/myorg/protos/main/service.protoGitHub — https://raw.githubusercontent.com/yourorg/specs/main/api.yamlConfiguration — MCPizer looks for config in this order: 1. -config command line flag (highest priority) 2. $MCPIZER_CONFIG_FILE environment variable 3Configuration is passed through the environment: MCPIZER_CONFIG_FILE, YOUR_API_TOKEN, YOUR_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Mcpizer's toolset — github, grpc, url and 2 more — is a fair guide to whether it matches your workflow. It is maintained by i2y; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
