Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.

@followed by the MCP server name and your instructions, e.g., "@marketnow-mcpverify this Agent Trust Card and check if it's revoked"
That's it! The server will respond to your query, and you can continue using it as needed.

Data and site questions go to the marketplace repo; protocol questions to UTA; everything else lives here.
MarketNow doesn't sell AI tools. It determines whether AI agents should be allowed to trust and execute them.
What is MarketNow?
MarketNow is trust infrastructure for AI agents: a hosted registry that verifies skills, credentials and domains across 68,388 indexed MCP servers (132,737 tracked across GitHub, npm and PyPI), with signed skill submissions, revocation checks and a 9-tool MCP API.
Every indexed entry is security-first scored. The MCP API is free — 68,387 of the 68,388 indexed servers are free to install (paid: 1 in the public stats API).

The 9 MCP tools (endpoint v1.15.0)
Endpoint tracks the npm train: v1.15.0 (2026-09-26 — repository-field repair →
alicelabs-llc/MARKETNOW, npm ↔ endpoint lockstep); previously v1.14.1 (2026-09-20).
The MCP server exposes 9 tools, all under the marketnow_* namespace so Claude Desktop, Cursor, Cline, LangChain and LlamaIndex can disambiguate them at tool-choice time:
# | Tool | What it does |
1 |
| Verify any AI-agent credential (JWT, W3C VC, MCP Card, ATC v3, A2A, EAT-AI, ZTA, X.509) through the UTA 12-stage verification pipeline |
2 |
| Translate a credential between 8 formats (ATC v3, JWT, W3C VC, A2A, EAT-AI, ZTA, MCP Card, X.509) losslessly via the Universal Trust Schema |
3 |
| List the 8 supported credential formats with their algorithms and status |
4 |
| Get the 12-stage verification pipeline details |
5 |
| Scam checker: returns a domain risk score with reasons |
6 |
| Search the registry of indexed MCP servers (GitHub, npm, PyPI), security-first scored |
7 |
| Check revocation of an Agent Trust Card or CA key against the signed Revocation Registry (MNR-CRL-1.0) + live ledger |
8 |
| Cryptographically fingerprint MCP tool definitions (OWASP MCP Cheat Sheet) with RFC 8785 JCS + SHA-256 |
9 |
| Publish a skill to the catalog: validated and Sentinel-scanned (injection patterns, embedded secrets, dangerous capabilities) |
Tool contract: deterministic marketnow_ snake_case names · intent-oriented descriptions · strict JSON-Schema parameters · structured { content, isError } responses.
Quick start
Connect any MCP client (Streamable HTTP)
{
"mcpServers": {
"marketnow": {
"url": "https://www.marketnow.site/api/mcp"
}
}
}Run the MCP server
npx -y marketnow-mcpRun it in Docker (audited repo tree, published by CI)
docker run -i --rm ghcr.io/alicelabs-llc/marketnow-mcp:1.15.0
# or register it in the Docker MCP Toolkit:
docker mcp gateway add --docker ghcr.io/alicelabs-llc/marketnow-mcpCline
Paste the ready block from integrations/cline/cline_mcp_settings.json into Cline → MCP Servers → Configure. The repo also ships .clinerules/ house rules. Guide: integrations/cline/README.md.
Cursor
Open this repo as your Cursor workspace — .cursor/mcp.json auto-registers the server, and .cursor/rules/marketnow.mdc teaches Cursor the house rules. Guide: integrations/cursor/README.md.

Source of truth: https://www.marketnow.site/api/stats.json — CI fails if any surface diverges.
Security model
Two levels:
L1 — index certification: all 68,388 entries pass 10 metadata/security checks before being indexed.
L2 — Sentinel scans: shipped npm tarballs are scanned (2,839 to date) for injection patterns, embedded secrets and dangerous capabilities. Skills that fail are quarantined and published in the transparency report.
Conformance
Canonical conformance vectors for the UTA pipeline: /uta/conformance/vectors/_index.json (schema 1.5.0).
