Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account karank2512 for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

tell: buying signals with receipts's local MCP server; no sign-in required; STDIO.

No AI overview yet: these facts come from the registry entry and the server itself.

Installation

In SourceWeft

Open tell: buying signals with receipts in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

README

tell-mcp

MCP server for tell, the open-source buying-signals pipeline. It lets Claude Desktop, Cursor or any MCP client ask which accounts are in market and why, with a receipt URL behind every signal (a job board, an SEC Form D filing, a news item). It runs locally over stdio and reads tell's public static JSON: no key, no account.

Quickstart

Claude Desktop (claude_desktop_config.json) or Cursor (~/.cursor/mcp.json):

json

{  "mcpServers": {    "tell": {      "command": "uvx",      "args": ["tell-mcp"],      "env": { "TELL_BASE_URL": "https://karank2512.github.io/tell-data" }    }  }}

{  "mcpServers": {    "tell": {      "command": "uvx",      "args": ["tell-mcp"],      "env": { "TELL_BASE_URL": "https://karank2512.github.io/tell-data" }    }  }}

Restart the app and ask: "Which of these ten domains are in market and why?"

Tools

Tool	Input	Output
`watch_accounts`	`domains`, `watchlist`	v0: the intake form link prefilled with the domains; the watchlist appears after the nightly job
`in_market`	`watchlist`, `since_days` (7), `min_score` (6.0), `families`	`[{domain, name, score, heat, top_contributions[:3]}]`, highest score first
`explain`	`domain`	Every contribution with its receipt URL, plus "why not higher" (signals that decayed in the last 30 days)
`events`	`domain`, `since`, `types`	Contributions and counted postings, newest first, at most 200, each with a URL
`coverage`	`domains`	Per domain: job board, SEC CIK, news feed, or "not monitored"

Prompt why_now_email(domain): the two-sentence "why now" for an outreach email, built from the top two signals with their receipt URLs. Tool descriptions ask the agent to cite the url of every signal it mentions and to call explain before writing outreach copy.

Configuration

Variable	Default	Meaning
`TELL_BASE_URL`	`https://karank2512.github.io/tell-data`	The static site to read
`TELL_API_KEY`, `TELL_API_URL`	unset	Both set: read companies and watchlists from the FastAPI service with a Bearer key
`TELL_INTAKE_FORM_URL`	unset	Intake form for `watch_accounts` (default: the repo's "Watch these domains" issue form)

v0 limitations

watch_accounts returns a prefilled link; it does not create the watchlist.
in_market reads public watchlists only (api/v0/watchlists/{slug}.json).
events has no raw event endpoint to read: it lists the scored contributions and the counted postings behind them.
Data refreshes with each ingest run (four a day); a domain quiet for 180 days has no file and reads as "not monitored".

When the FastAPI service is deployed, setting TELL_API_KEY and TELL_API_URL switches company and watchlist reads to it without any other change.
