MCP server for evidence-based commercial due diligence on digital marketplaces.
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"marketplace-reality-check-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

# Marketplace Reality Check MCP A local MCP server for founders, indie developers, and autonomous revenue agents deciding whether a digital marketplace deserves build time. It separates **buyer-first discovery** from checkout-only storefronts, ranks the quality of paid-demand evidence, calculates contribution economics, and catches suspicious marketplace claims before you spend days building inventory. ## Tools - `preflight_evidence` — free demand-signal classifier. - `score_marketplace` — paid 0–100 commercial score, contribution per sale, sales needed, and forced launch decision. - `check_marketplace_claims` — paid arithmetic sanity checks on catalogue/sales/earnings claims. - `compare_marketplaces` — paid side-by-side ranking of candidate channels. ## Install from GitHub ```bash pip install git+https://github.com/OkuboHeavyIndustries/marketplace-reality-check-mcp.git ``` Then configure your MCP client to run: ```text marketplace-reality-check ``` Paid tools require the license issued by MCP Marketplace: ```text MCP_LICENSE_KEY=mcp_live_... ``` Optional if the final marketplace listing slug changes: ```text MCP_MARKETPLACE_SLUG=marketplace-reality-check ``` ## Privacy Runs locally over stdio. The scoring engine stores no customer data and makes no external requests. Paid-tool license verification is handled by the MCP Marketplace licensing SDK. ## Development The scoring engine is intentionally isolated from MCP dependencies and can be tested with the Python standard library: ```bash python -m unittest discover -s tests -v ``` ## Commercial model Suggested listing: **US$15 one-time** with `preflight_evidence` available as the free taste and the remaining tools license-gated.
