Summary
Wraps the StupidAPIs passive aggression detection endpoint in a single MCP tool that analyzes text for hostile undertones. You get a severity score from 0 to 100, specific flagged phrases with explanations, a plain English translation of what's actually being said, and suggestions for direct responses. Requires an X-API-Key from StupidAPIs. Most useful when you're reviewing workplace emails, Slack threads, or customer messages and need to flag communication that's technically polite but clearly adversarial. Part of the Pipeworx gateway, so you can either use this standalone or connect to the full suite of 250+ data sources.

Tools
| Tool | Description |
|---|---|
passive_aggression_detect | Analyze text for passive-aggressive language. Returns severity score (0-100), flagged phrases with explanations, plain English translation of the subtext, and suggested direct responses. Use when reviewing emails, messages, or conversations to identify underlying hostility. |
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"passive-aggression": {
"url": "https://gateway.pipeworx.io/passive-aggression/mcp"
}
}
}
What this endpoint actually serves
tools/list at https://gateway.pipeworx.io/passive-aggression/mcp returns the tools in the table
above plus the shared Pipeworx meta-tools — ask_pipeworx,
discover_tools, search_within, remember/recall and the rest of the
gateway-wide set. So the tool count you see is larger than this table: a
single-pack endpoint currently lists roughly 30 shared tools alongside the
pack's own. The connection's initialize response states its exact scope, and
is the authoritative answer for a given day.
This is deliberate, not multiplexing by accident. The meta-tools are what let a
scoped connection answer a question this pack does not cover — via
ask_pipeworx, which routes across the whole catalog — without you adding a
second MCP server. There is currently no way to mount a pack endpoint without
them; if the extra schemas cost you more context than the routing is worth,
connect to the full gateway once rather than to several pack endpoints.
Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Both URLs reach the same gateway and the same 1476+ data sources. The
only difference is which pack's tools are listed directly; ask_pipeworx
reaches all of them from either one.
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:
ask_pipeworx({ question: "your question about Passive Aggression data" })
The gateway picks the right tool and fills the arguments automatically.
