failmodes-mcp
MCP server for the Fail Modes taxonomy — a machine-readable knowledge base of AI system failure modes.
Provides four tools over 100+ canonical failure mode records spanning factuality, alignment, planning, code generation, instruction following, and more.
Tools
| Tool | Description |
|---|---|
search_failure_modes |
Search by symptom text or keyword phrase. Returns ranked matches. |
get_failure_mode |
Retrieve the full structured record for a failure mode by ID slug. |
list_categories |
List all taxonomy categories with descriptions and mode counts. |
list_modes |
List all modes, optionally filtered by category ID. |
Quick Start
No installation required — run directly with npx:
npx failmodes-mcp
Configuration
Claude Desktop
Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):
{
"mcpServers": {
"failmodes": {
"command": "npx",
"args": ["-y", "failmodes-mcp"]
}
}
}
Cursor / VS Code
Add to your MCP settings file:
{
"mcpServers": {
"failmodes": {
"command": "npx",
"args": ["-y", "failmodes-mcp"]
}
}
}
Remote (no install required)
A hosted Streamable HTTP version is also available — no npm package needed:
{
"mcpServers": {
"failmodes": {
"url": "https://www.failmodes.com/api/mcp"
}
}
}
How It Works
On first tool call, the server fetches current taxonomy data from failmodes.com and caches it in memory for the duration of the session. Requires internet access.
The stdio transport makes this compatible with any MCP client that supports running local processes (Claude Desktop, Cursor, VS Code, etc.).
