AI foundry unable to connect with Azure MCP server

Open matrahul opened this issue 2 months ago • 7 comments

Is there any MCP.json file for Azure MCP server available ? so instead of adding all the tools one by one and creating an instruction for AI Ageny to use. we can just use that file to activate all the tools in one go and Is there Container image to deploy that. I do not want to use the Github co-pilot to do that. we want to use that in a production and we want to use our own client to perform the deployment and other tasks via AI foundry.

Hi @matrahul thank you for reaching out. Yes, there are instructions on the README.md for Docker to deploy as a local mcp server.

We will have updated docker images and instructions in November+ for remote mcp server support, including easy deploying to ACA/AKS to use from Azure AI Foundry. @anuchandy is working on this area now.

@diberry is our doc writer and will be updating the docs/learn site with instructions on the various installer options too. Until then, the README.md is your best bet for information like this: https://github.com/microsoft/mcp/blob/main/servers/Azure.Mcp.Server/README.md

@joshfree thanks for the update however I'm unable to connect the AI Foundry agent to MCP server. I can use the tools via remote client but somehow it doesn't connects with AI agent for any LLM or AI request. The flow directly pulls tools from MCP server and provides the answer.

Hi @matrahul this issue tracks updates for the documentation you're seeking https://github.com/microsoft/mcp/issues/789

Hi @joshfree @anuchandy , how can we authenticate the MCP server with Azure. I have tried deploying it under the container app but to access the tools it should authenticate it with Azure. How does it work? Readme doc doesn't help.

MCP Server still has some binary issues where it doesn't connect or provide any tools or output. where i found that The binary is missing a required C library function (__strdup). The Microsoft image is missing some dependencies that our Alpine base image doesn't have. We need to install the missing dependencies! T The issue was resolved by adding gcompat to the Alpine Linux container: RUN apk add --no-cache
nodejs
npm
bash
curl
gcompat

Root Cause

  • Alpine Linux uses musl libc
  • Azure MCP binary requires glibc
  • Symbol __strdup is a glibc internal function
  • Docker Desktop masked the issue with emulation

Solution Implemented

  • Migrated from Alpine to Debian base image
  • Native glibc support (no compatibility layer)
  • Multi-stage build for optimization
