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. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 2 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability77
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 171 tokens (~85/item across 2 items; 2 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management50
- Stability check failed: schema churn in the 30 days we've observed: 2 tool removals, 0 breaking changes, 0 auth/transport breaks, 0 additions. See how to fix → Fail
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
run402_quickstart ~65
How an agent gets a Postgres database, static site, serverless functions, storage and email on run402 with no signup — paid per-use with x402 USDC on Base. Returns the 60-second start, key URLs, and the free-testnet path.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
x402_price_check ~57
Inspect any https URL for x402 pricing: performs an unpaid request and decodes the 402 challenge (price, network, asset, recipient). Free — no payment is made.
| Name | Type | Req | Description |

| url | string | yes | https URL to probe |

How do I install the Run402 MCP server?
Run402 is a hosted endpoint at https://mcp.run402.com/mcp, 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.

What is the Run402 MCP server?
Run402 is an MCP server listed in the public MCP registry as com.run402/mcp. x402 pay-per-call infra for agents: $0.03 image generation, Postgres, auth, storage, functions. This page covers its hosted endpoint (https://mcp.run402.com/mcp).
Is the Run402 MCP server safe to use?
Run402 scores 72 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 Run402 MCP server expose?
Run402 exposes 2 tools: run402_quickstart, x402_price_check. Their descriptions and schemas cost roughly 122 tokens of context every time the server is loaded.
Does the Run402 MCP server require authentication?
No. We connected to Run402 without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Run402 MCP server still maintained?
Run402 is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
