MCP-Anything turns any data source into a fully implemented MCP server — from a plain-language brief describing what agents should be able to do. It also works directly from codebases, OpenAPI specs, gRPC protos, and GraphQL schemas. Two modes, one tool.

Quick start

**1. Install**

pip install mcp-anything
export ANTHROPIC_API_KEY=sk-...

**2. Write a brief** — describe your domain and point at your data source

# my-api.yaml
server_name: payments-mcp
domain_description: >
  A payment API for managing customers, invoices, and subscriptions.
use_cases:
  - "Create a customer with email and name"
  - "Issue an invoice and send it to the customer"
  - "Create and cancel subscriptions"
  - "Issue refunds"
data_source_path: ./openapi.json   # local file or URL
data_source_kind: openapi          # openapi | graphql | grpc
auth_method: bearer_token
backend_target: fastmcp

**3. Build**

mcp-anything build --brief my-api.yaml -o ./my-mcp-server

**4. Run**

cd my-mcp-server
pip install -e .
python -m mcp_payments_mcp.server

That's it. You now have a running MCP server. Add it to your agent:

{
  "mcpServers": {
    "payments": { "command": "python", "args": ["-m", "mcp_payments_mcp.server"] }
  }
}

`build` — brief-driven (recommended)

The LLM reads your brief, groups related operations into ergonomic tools, writes agent-
