Bring your own custom MCP server
Run your own MCP server and connect it to Spojit. Its tools are auto-discovered and ready to use in your workflows, called directly as a step in Direct Mode or handed to an agent in Agent Mode.

Your stack has tools no vendor will ever publish an MCP server for: internal services, in-house APIs, bespoke logic. Wrap them as your own MCP server, connect it to Spojit, and those tools become first-class steps in your workflows. Use them deterministically in Direct Mode, or expose them to an AI agent in Agent Mode and let it choose. Spojit does not need to know your tools in advance; it discovers them from your server.
Host your MCP server at a publicly reachable HTTPS endpoint (Spojit connects remotely, so a localhost or private-network address will not work), point Spojit at that URL, and supply whatever auth it expects. Its tools are auto-discovered and ready to use in Direct Mode or Agent Mode.
Custom MCP server inside a durable workflow
Use your tools in Direct Mode
Call a specific tool from your server as a deterministic workflow step, with the exact inputs you map in, no agent reasoning involved.
Hand your tools to an agent
Expose your server to an AI agent in Agent Mode and let it pick the right tool for the task while the workflow runs.
Reuse internal systems as tools
Wrap an internal service once as an MCP server, then reuse its tools across every workflow and agent you build.
Why teams run this on Spojit
With Spojit
- Your custom tools run as first-class workflow steps, on the same durable execution as built-in connectors.
- Use the same server two ways: deterministically in Direct Mode, or handed to an agent in Agent Mode.
- Spojit does not need to know your server in advance. You bring it, its tools are auto-discovered, and they are ready to use.
Custom MCP server, answered
What is a custom MCP server?
It is an MCP server you run that exposes your own tools. Connect it to Spojit and those tools become steps you can use in any workflow, the same way built-in connectors work.
Can I use my internal services?
Yes, as long as the server is reachable over the internet. Spojit connects to your MCP server remotely, so it cannot reach one running only on your laptop or inside a private network. Host it at a public HTTPS endpoint (directly, or through a tunnel or gateway), point Spojit at that URL, and it calls the tools like any other step.
Does Spojit need to know about my server in advance?
No. Once you connect it, Spojit auto-discovers your tools, so you can call a specific one in Direct Mode or expose the whole server to an agent in Agent Mode and let it choose.
What is possible depends on your plan and authorized access. Connecting your own MCP server depends on it being reachable over the internet and on the auth and access you provide. You can request a feature or integration any time, and we will get in touch to figure out how to make it work.
