graphify-mcp fails on fresh installation with ImportError: cannot import name 'AnyUrl' from mcp.types #2279
Description
Environment
- OS: Windows 11
- Python: 3.13.5
- Graphify: 0.9.29
- Installed using:
uv tool install "graphifyy[mcp]"
Steps to reproduce
- Install Graphify:
uv tool install "graphifyy[mcp]"- Build a graph:
graphify extract . --code-only- Run the MCP server:
graphify-mcp D:\apps\ims\graphify-out\graph.jsonExpected behavior
The MCP server should start and wait for client connections.
Actual behavior
The server immediately exits with the following error:
Traceback (most recent call last):
File "...graphify\serve.py", line 1116, in _build_server
from mcp.types import AnyUrl
ImportError: cannot import name 'AnyUrl' from 'mcp.types'
...
ImportError: mcp not installed. Run: pip install "graphifyy[mcp]"
Additional information
The installation completed successfully:
- graphify 0.9.29
- mcp 2.0.0
- mcp-types 2.0.0
The CLI (graphify) works correctly.
graphify extract also works correctly.
The problem only occurs when starting the MCP server (graphify-mcp or python -m graphify.serve).
It looks like Graphify imports AnyUrl from mcp.types, but this symbol is not available in the installed mcp package.
I can reproduce this without Antigravity.
The following command also fails:
graphify-mcp D:\apps\ims\graphify-out\graph.jsonIt immediately throws:
ImportError: cannot import name 'AnyUrl' from 'mcp.types'
So this appears to be an issue in the MCP server itself rather than the Antigravity integration.
I investigated the issue further.
graphify.serve imports:
from mcp.types import AnyUrlThis is located at:
graphify/serve.py:1116
However, the installed package:
C:\Users\<username>\AppData\Roaming\uv\tools\graphifyy\Lib\site-packages\mcp\types\__init__.py
does not export AnyUrl.
Running:
Select-String -Path "...graphify\serve.py" -Pattern "AnyUrl"returns several usages.
Running:
Select-String -Path "...mcp\types\__init__.py" -Pattern "AnyUrl"returns no results.
So it appears Graphify expects AnyUrl from mcp.types, but the version of mcp installed by:
uv tool install "graphifyy[mcp]"does not provide it.

I can confirm this issue on another Windows machine.
Environment
Installed using:
python -m uv tool install "graphifyy[mcp,gemini,sql]"Result
Everything except MCP works correctly:
The MCP server fails immediately with:
Cursor MCP also fails with the same traceback.
My installation contains:
Looks like another confirmation that Graphify 0.9.29 is incompatible with MCP 2.0.0.

I was able to reproduce the issue on a fresh installation. The root cause appears to be an incompatibility between the current graphify-mcp release and newer versions of the mcp SDK. Specifically,
graphify-mcpimportsAnyUrlfrommcp.types,but that symbol is no longer available in the latest mcp versions, resulting in:ImportError: cannot import name 'AnyUrl' from 'mcp.types'As a temporary workaround, the following steps resolve the issue:
After downgrading to
mcp==1.29.0,graphify-mcpstarts and works as expected.It would be helpful to either:
update
graphify-mcpto support the latestmcpSDK, orpin the compatible
mcpversion in the package dependencies until compatibility is restored.smartweb-dev commentedon Jul 29, 2026
Thanks! My installation uses uv tool install "graphifyy[mcp,gemini,sql]" rather than a global pip install. Is there a recommended way to pin mcp==1.29.0 inside the uv tool environment, or is reinstalling via pip currently the only supported workaround?

Fixed in v0.9.30 (same root as #2277): mcp is capped below 2.0, resolving to 1.29.0, so graphify-mcp starts on a fresh install again. https://github.com/Graphify-Labs/graphify/releases/tag/v0.9.30
Merge v8 (0.9.30) into mcp2-support
