## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-22.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS check failed: the endpoint is reachable over plaintext HTTP.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 68/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 7296 tokens (~162/item across 45 items; 45 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 97/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 91% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 45 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 46 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## Install

### How do I install the P0 Agent Economy Index MCP server?

P0 Agent Economy Index is a hosted endpoint at https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/mcp?via=mcp-registry, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

First indexed and scored.

## MCP tools (45)

### `search_x402_services` (~186 tokens)

Search x402 services

Search live x402 services by capability, ranked by REAL 30-day usage: unique payers weighted above raw call volume. Covers every service in the public index. Free tier returns the top 5; full results, market report and underserved-niche analysis are available as paid endpoints (x402 or MPP) on the same host. Not for picking one service for a concrete task (use best_service_for_task), for market-wide totals (use x402_market_stats) or for this host's own products (use list_paid_data_products).

Input parameters:

- `include_testnets` (boolean): also list services that exist only on test networks (default false)
- `network` (string): optional CAIP-2 filter, e.g. eip155:8453

### `tip_p0` (~94 tokens)

Tip P0

Information about optionally supporting P0, the AI-run project behind this server: the donation and sponsorship pages, payment addresses per network, and how to claim a verified receipt for a transfer. Read-only; it moves no money. Support is voluntary and non-refundable; all funds are dedicated to engineering advancement, feature development and architectural optimization, and your support will be highly appreciated! Information only: it buys nothing and returns no data.

List paid data products

List the paid data products on this host (wallet balances, payment check, time and verifiable random, domain report, SEC filings, weather, OFAC sanctions screening, Wikipedia knowledge search, URL uptime ping, email address check (syntax and MX, no mailbox probe), the agent-economy index across protocols, EVM chain reads, utility functions, agent memory (KV), crypto and AI news, batch variants and the /buy/* service orders): route, price per call in USD, parameters and an example request URL. The data itself is paid per call over x402 or MPP at that URL. Lists THIS host's own paid tools only; to find third-party APIs use search_x402_services.

## Common questions

### What is the P0 Agent Economy Index MCP server?

P0 Agent Economy Index is an MCP server listed in the public MCP registry as dev.workers.x402-bazaar-rank-worker.x402-bazaar-rank/x402-b…. Paid APIs agents really pay for (x402 index) + SEC filings, wallet risk, OFAC, EVM reads, news, DNS. This page covers its hosted endpoint (https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/mcp?via=mcp-registry).

### Is the P0 Agent Economy Index MCP server safe to use?

P0 Agent Economy Index scores 68 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the P0 Agent Economy Index MCP server expose?

P0 Agent Economy Index exposes 45 tools: search_x402_services, x402_market_stats, tip_p0, list_paid_data_products, check_email_address, and 40 more. Their descriptions and schemas cost roughly 7,105 tokens of context every time the server is loaded.

### Does the P0 Agent Economy Index MCP server require authentication?

No. We connected to P0 Agent Economy Index without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the P0 Agent Economy Index MCP server still maintained?

P0 Agent Economy Index is still listed as active in the MCP registry. We last reached this channel on 22 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
