Mcp2cli

# mcp2cli

Turn any MCP server, OpenAPI spec, or GraphQL endpoint into a CLI at runtime. No codegen.

## Install

```bash
# Run directly (no install needed)
uvx mcp2cli --help

# Or install
pip install mcp2cli
```

## Core Workflow

1. **Connect** to a source (MCP server, OpenAPI spec, or GraphQL endpoint)
2. **Discover** available commands with `--list` (or filter with `--search`)
3. **Inspect** a specific command with `<command> --help`
4. **Execute** the command with flags

```bash
# MCP over HTTP
mcp2cli --mcp https://mcp.example.com/sse --list
mcp2cli --mcp https://mcp.example.com/sse create-task --help
mcp2cli --mcp https://mcp.example.com/sse create-task --title "Fix bug"

# MCP over stdio
mcp2cli --mcp-stdio "npx @modelcontextprotocol/server-filesystem /tmp" --list
mcp2cli --mcp-stdio "npx @modelcontextprotocol/server-filesystem /tmp" read-file --path /tmp/hello.txt

# OpenAPI spec (remote or local, JSON or YAML)
mcp2cli --spec https://petstore3.swagger.io/api/v3/openapi.json --list
mcp2cli --spec ./openapi.json --base-url https://api.example.com list-pets --status available

# GraphQL endpoint
mcp2cli --graphql https://api.example.com/graphql --list
mcp2cli --graphql https://api.example.com/graphql users --limit 10
mcp2cli --graphql https://api.example.com/graphql create-user --name "Alice"
```

## CLI Reference

```
mcp2cli [global options] <subcommand> [command options]

Source (mutually exclusive, one required):
  --spec URL|FILE       OpenAPI spec (JSON or YAML, local or remote)
  --mcp URL             MCP server URL (HTTP/SSE)
  --mcp-stdio CMD       MCP server command (stdio transport)
  --graphql URL         GraphQL endpoint URL

Options:
  --auth-header K:V       HTTP header (repeatable, value supports env:/file: prefixes)
  --base-url URL          Override base URL from spec
  --transport TYPE        MCP HTTP transport: auto|sse|streamable (default: auto)
  --env KEY=VALUE         Env var for stdio server process (repeatable)
  --oauth                 Enable OAuth (authorization code + PKCE flow)
  --oauth-client-id ID    OAuth client ID (supports env:/file: prefixes)
  --oauth-client-secret S OAuth client secret (supports env:/file: prefixes)
  --oauth-scope SCOPE     OAuth scope(s) to request
  --cache-key KEY         Custom cache key
  --cache-ttl SECONDS     Cache TTL (default: 3600)
  --refresh               Bypass cache
  --list                  List available subcommands
  --search PATTERN        Search tools by name or description (implies --list)
  --fields FIELDS         Override GraphQL selection set (e.g. "id name email")
  --pretty                Pretty-print JSON output
  --raw                   Print raw response body
  --json                  Force valid JSON for every command. --list emits a JSON array;
                          MCP calls emit the full envelope (structuredContent, isError).
  --toon                  Encode output as TOON (token-efficient for LLMs)
  --head N                Limit output to first N records (arrays)
  --version               Show version

Bake mode:
  bake create NAME [opts]   Save connection settings as a named tool
  bake list                 List all baked tools
  bake show NAME            Show config (secrets masked)
  bake update NAME [opts]   Update a baked tool
  bake remove NAME          Delete a baked tool
  bake install NAME         Create ~/.local/bin wrapper script
  @NAME [args]              Run a baked tool
