Let your agents build their own tools

Turn any API into a personalized MCP so your agents can get things done reliably.

We've seen dozens of devs being torn between giving their agents enough freedom to fetch the data they need and still guaranteeing that every call stays secure, fast, and actually works.

Glue APIs into stable capabilities.

Merge Multiple APIs

Combine endpoints and APIs into custom capabilities

No more juggling dozens of specific tools. Create unified capabilities that work across multiple services.

Production Ready

Secure, fast, and guaranteed to work

Built for production deployments with stability guarantees even as upstream APIs change.

Bespoke Agent Tools

Custom tools that agents actually need

Stop building generic tools. Create purpose-built capabilities that match your specific workflows and business logic.

How MCPglue Works

1

Merges multiple endpoints and APIs into custom tools - we call them capabilities
2

Exposes them via one server that abstracts away endpoints and API calls
3

Acts like a repository pattern that stays stable even as upstream APIs or mappings change

Use MCPglue to:

Stitch Stripe and HubSpot together

Build cross-API workflows

Fetch transactions in Stripe and update them in HubSpot reliably.

Create Ambient Agents

Build agents that react to app triggers and events

Create agents that monitor your systems and respond automatically to events, triggers and webhooks.

Wrap your own APIs

Make your own APIs accessible by any agent

Turn your internal APIs and services into agent-friendly capabilities with built-in validation and error handling.
