[BUG] [BUG] Claude Desktop MCP tools failing with "Required" parameter error

[BUG] Claude Desktop MCP tools failing with parameter validation error - July 23, 2025

Bug Description

Claude Desktop MCP tools suddenly stopped working on July 23, 2025. All MCP tools are failing with parameter validation errors when called by Claude Desktop, despite the MCP servers themselves functioning correctly.

Environment

• Date: July 23, 2025
• Platform: Multiple computers affected (confirming this is not a local configuration issue)
• Claude Desktop Version: [Please check your version]
• Operating System: [Please specify your OS]

Expected Behavior

MCP tools should receive proper parameters when called by Claude Desktop and execute successfully as they did until July 22, 2025.

Actual Behavior

• Claude Desktop calls MCP tools without required parameters
• All tool calls result in validation errors
• Error indicates "expected": "object", "received": "undefined"
• MCP servers themselves are working (connection established, communication functional)

Reproduction Steps

1. Have any MCP server configured and running (e.g., filesystem)
2. Try to use any MCP tool through Claude Desktop interface
3. Observe the parameter validation error in MCP logs

Error Logs

2025-07-23T04:39:51.994Z [filesystem] [info] Message from client: {"method":"tools/call","params":{"name":"list_directory"},"jsonrpc":"2.0","id":16} { metadata: undefined }
2025-07-23T04:39:51.995Z [filesystem] [info] Message from server: {"jsonrpc":"2.0","id":16,"result":{"content":[{"type":"text","text":"Error: Invalid arguments for list_directory: [\n  {\n    \"code\": \"invalid_type\",\n    \"expected\": \"object\",\n    \"received\": \"undefined\",\n    \"path\": [],\n    \"message\": \"Required\"\n  }\n]"}],"isError":true}} { metadata: undefined }

Analysis

1. MCP Server Status: ✅ Working correctly (connection established, responds to calls)
2. Client-Server Communication: ✅ Working (messages are being exchanged)
3. Parameter Passing: ❌ Claude Desktop is not passing required parameters to MCP tools

Additional Context

• Timeline: Worked perfectly until July 22, 2025, suddenly broke on July 23, 2025
• Scope: Multiple users on different computers experiencing the same issue simultaneously
• Impact: All MCP functionality is currently broken in Claude Desktop
• Workaround: None available - this appears to be an internal Claude Desktop issue

Root Cause Assessment

This appears to be a regression introduced in Claude Desktop's MCP tool calling mechanism, where the application is no longer properly packaging tool parameters before sending them to MCP servers.

Priority

High - This completely breaks MCP functionality for all users, which is a core feature of Claude Desktop.

---

Note: This issue appears to coincide with reported Claude service instabilities on July 23, 2025, suggesting this may be related to a recent update or backend change.

[teticio]

I notice that it affects all MCP tool calls after the first. Happens with local and connector type remote MCP servers. In the POST request to my /mcp endpoint I notice that the params only contain the name of the tool but not the arguments:

First call:
POST /mcp {"method":"tools/call","params":{"name":"doThing","arguments":{"withThis":"stuff"}},"jsonrpc":"2.0","id":9}

Subsequent calls:
POST /mcp {"method":"tools/call","params":{"name":"doThing"},"jsonrpc":"2.0","id":13}

It looks like a bug in the backend, because I am seeing the same thing with various versions of Claude Dektop, both on Mac and on (ahem) Linux.

Same here, using local and remote proxy connection that worked fine on 22.07.2025. Same issue is with accessing official atlassan api to access jira tickets. Same behavior, first call in a reponse is fine, any subsequent fails. New response gets new first attempt, then fails again. Tried restarting, reinstalling and cleaning, nothing helped.

log attached, but i suspect more of the same...

mcp-server-office-filesystem-proxy.log

relevant parts i think:
1st call:
2025-07-23T09:35:33.597Z [office-filesystem-proxy] [info] Message from client: {"method":"tools/call","params":{"name":"read_file","arguments":{"path":"E:\TT4T\ClaudeMCP\ServerTools\mcp_registry.py"}},"jsonrpc":"2.0","id":4} { metadata: undefined }
-> OK response

2nd call:
2025-07-23T09:35:39.376Z [office-filesystem-proxy] [info] Message from client: {"method":"tools/call","params":{"name":"read_file"},"jsonrpc":"2.0","id":5} { metadata: undefined }
-> Failed response:
Exception: ToolError: Error calling tool 'read_file': 1 validation error for call[read_file]
path
Missing required argument [type=missing_argument, input_value={}, input_type=dict]
For further information visit https://errors.pydantic.dev/2.11/v/missing_argument
.... bla bla server error

the "arguments" parameter is missing.

[0913vision]

Same issue here. In my case, running npx -y @modelcontextprotocol/server-filesystem directly from the terminal works fine. However, in Claude Desktop, all MCP calls after the first one result in Cannot convert undefined or null to object.

[rhs2207]

Same for me too
all MCP calls result in Cannot convert undefined or null to object.

[phodat]

Same here, mcp.log showing similar errors for all mcp tools:
Message from server: {"jsonrpc":"2.0","id":17,"result":{"content":[{"type":"text","text":"Field 'pathInProject' is required for type with serial name 'org.jetbrains.mcpserverplugin.general.PathInProject', but it was missing at path: $"}],"isError":true}}
