n8n MCP server tool descriptions cause excessive token usage in Claude, hitting conversation limits quickly

Bug Description

The n8n MCP server (@n8n/n8n-mcp) sends extremely verbose tool descriptions in every exchange with Claude Desktop, causing conversations to hit token limits after just 2-3 messages. This makes the integration nearly unusable.

To Reproduce

1.Install n8n MCP server via Claude Desktop config:
json
"n8n-mcp": {
"command": "npx",
"args": ["-y", "@n8n/n8n-mcp"]
}

2. Start a conversation with Claude about n8n
3. Observe that conversation limits are reached within 10-20 messages or less

Expected behavior

Tool descriptions should be concise (under 200 characters)
Detailed documentation should be available via a separate endpoint or command
Users should be able to have extended conversations without hitting token limits
