[/why external mcp]

One URL is simpler than ten integrations.

You can build and maintain this stack yourself, or connect once and focus on product logic.

01 ->

No install

External MCP means no local Docker, no package setup, and no custom bridge code. Your client connects over HTTP.

02 ->

Open-data first

Most connected sources are public APIs. Munge keeps them unified behind a single MCP endpoint.

03 ->

Updated continuously

When upstream APIs evolve, we absorb interface changes so your prompts and tool routing can stay stable.

04 ->

Tool-shaped, not API-shaped

Each tool has a clean name, typed JSON schema, and model-friendly description. We handle source-specific payload formats.

[/pricing]

Open data. Free to use.

Public information should be accessible. Start free, ship fast, and self-host if you want full control.
