Very cool. How does it work when multiple installed MCP servers have overlapping functionality? Are MCPs going to have competing prompts saying for example they’re the best to choose for OCR etc?

Yes absolutely. And if you install an mcp server with a poorly written prompt, your sota llm might try to use it for everything. Prompt injection attacks will also be a thing. Depending on how this all plays out, we're in for interesting times.

The number of threads of people asking how to permanently accept all tool use so they don't have to accept them manually...

I have been playing around with MCP, and one of its current shortcomings is that it didn’t support OAuth. This means that credentials need to be hardcoded somewhere. Right now, it appears that a lot of MCP servers are run locally, but there is no reason they couldn’t be run as a service in the future. There is a draft specification for OAuth in MCP, and hopefully this is supported soon.

There's open source package that allows delaying providing credentials to MCP server to runtime / via MCP tool call: https://github.com/supercorp-ai/superargs

For hosted MCPs: https://supermachine.ai

You could use Nango for the OAuth flow and then pass the user’s token to the MCP server: https://nango.dev/auth

Free for OAuth with 400+ APIs & can be self-hosted
