AgentRails provides x402 payment tools for AI agents. Enables autonomous agent-to-agent and agent-to-API payments using the x402 HTTP payment protocol with USDC on blockchain. Tools include x402 payment execution and history, agent lifecycle management, billing usage tracking, and spending policy enforcement. Built for enterprise AI agent workflows that require programmatic payment capabilities.

MCP readiness

D · 42/100

Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here D, 28.0/100), which weighs availability, conformance, p95 speed and descriptor. How the two differ

Valid MCP handshake	0/10	Handshake needs credentials (HTTP 401); not readable anonymously.
Live MCP endpoint	14/25	Endpoint requires authentication or payment (2922 ms); slow response -1.
Protocol revision	0/10	No protocol revision reported by initialize.
Signed descriptor	n/a	No MCP standard defines a signed server descriptor.
Uptime (30 days)	15/15	22/22 probes succeeded over 30 days (100%).
Tool declaration	0/10	No tools listed by tools/list.
Verified identity	5/10	Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Freshness + modern flags	4/5	seen in a source within 7 days.
Auth declaration	0/5	How to authenticate is not stated.

Applicable criteria total 90 points, scaled to 100.

Responsiveness: Slow (2922 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).

Measured 2026-11-11.

Nine criteria, the same as the A2A readiness score, read from our daily MCP probe (initialize + tools/list) and 30-day probe history. No MCP standard defines a signed server descriptor, so that criterion is n/a and the other 90 points are scaled to 100. Grades: A>=90, B>=75, C>=60, D>=40, F<40. Display only: search order uses the quality grade.

Compared with peers

Against 53,021 reachable MCP servers in our daily snapshot (2026-11-12 01:39 UTC). Display only; it does not change search order.

Readiness: Higher than 12% of peers; This listing 42 · peer median 81
Latency: Faster than 66% of peers; This listing 226 ms · peer median 326 ms

Where it loses the most points, and how to win them back

Live MCP endpoint −11 — Answer initialize and tools/list at the declared endpoint.
Now: Endpoint requires authentication or payment (2922 ms); slow response -1.
Valid MCP handshake −10 — Complete the MCP handshake without errors.
Now: Handshake needs credentials (HTTP 401); not readable anonymously.
Protocol revision −10 — Support the current protocol revision.
Now: No protocol revision reported by initialize.
