Available components
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 Security57
- 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 4 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
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- 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 Usability71
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 507 tokens (~126/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage67
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the Verifi MCP server?
Verifi is a hosted endpoint at https://verifi.cloud/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.

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 →
get_verify ~29
Poll until ready or failed. Honor retry_after_seconds while processing.
| Name | Type | Req | Description |
|---|---|---|---|
| verify_id | string | yes | – |
No output schema declared.
No examples provided.
unlock_verify ~94
Pass gate 2 for a ready chain and return the human result. This gate costs 2.90 USDC. Omit payment_signature first: standard x402-aware MCP clients handle the payment request and retry through MCP metadata automatically. Generic clients can pass the resulting x402 signature manually. Never pass a private key.
| Name | Type | Req | Description |
|---|---|---|---|
| payment_signature | – | – | – |
| verify_id | string | yes | – |
No output schema declared.
No examples provided.
verifi_info ~17
Service description, pricing, and rules.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
verify_claim ~216
Ask a real human to verify a claim. intent: what your agent is trying to do (max 2000 chars). claim: the claim a human should verify (max 4000 chars). agent_id: your wallet address (0x + 40 hex). Signs the x402 payments. callback_url: optional HTTPS endpoint for verify.ready or verify.failed. Use it to avoid an active polling loop; retain verify_id for recovery. payment_signature: optional manual compatibility input. Standard x402-aware MCP clients send the signed payment through request metadata automatically. Returns status "processing" with a verify_id. Prefer callback_url, or poll get_verify at the returned interval until status is "ready" or "failed". If ready, call unlock_verify. Only one active verify per agent_id at a time.
