How to: LangChain Trigger.dev MCP by usefulapi find_failed_runs_and_read_their_errors
Add Trigger.dev MCP by usefulapi to LangChain
-
01
Open pip install langchain-mcp-adapters and merge this in. Keep any servers already there.
from langchain_mcp_adapters.client import MultiServerMCPClient
client = MultiServerMCPClient({
"trigger-dev": {
"transport": "streamable_http",
"url": "https://trigger-dev.usefulapi.io/mcp",
}
})
tools = await client.get_tools()
-
02
Save the file and restart LangChain.
-
03
find_failed_runs_and_read_their_errors is surfaced through the client's prompt API, fetched by name. Unlike a tool, you invoke it deliberately — LangChain will not call it for you.
-
04
If it does not appear, check that Trigger.dev MCP by usefulapi is connected and that you are looking at its prompts rather than its tools.
get_tools() returns the server's tools as LangChain tools, ready for an agent. LangChain docs
Same prompt, other clients
Read from the server itself, by connecting to it and calling prompts/list on 14 November 2026.
A listing does not declare its prompts, so asking is the only way to know them, and this
is what the server actually offers rather than what its listing claims. Names only are
stored; connect the server for each prompt's arguments.
