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 Security92
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token. View diagnostics → Pass
- 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
- The authorisation server supports Client ID Metadata Documents, the current MCP client-registration mechanism. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability80
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 954 tokens (~34/item across 28 items; 4 tools + 24 resources), lean.Pass
- 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 Coverage87
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 53% of tool parameters carry a description.Partial
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

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 →

pubfi.route.execute ~171
Execute one exact GET or POST path through the authenticated PubFi account lane and the same Registry v2 matcher and typed executor as the HTTP gateway. Append :free only when the capability catalog publishes that exact account-scoped free variant.
| Name | Type | Req | Description |
|---|---|---|---|

| idempotency_key | string | – | – |
| method | string | yes | – |
| query | string | – | Exact ASCII raw query string without a leading question mark. |
| raw_path | string | yes | Exact original URI path consumed by the Registry matcher. Segments use canonical unreserved ASCII only; percent escapes, dot segments, query, fragment, and backslash are forbidden. |

Structured output declared, but exposes no named fields.
No examples provided.
pubfi.substrate.runtime_upgrade.verify ~160
Verify one reviewed Substrate System.apply_authorized_upgrade extrinsic through the authenticated account lane. Supply the expected Blake2b-256 hash of the FRAME System AuthorizedUpgrade code payload, not the active :code hash at the apply block. The server streams and discards provider runtime code, persists only a compact proof, and returns independent comparison evidence.

How do I install the PubFi MCP server?
PubFi MCP is a hosted endpoint at https://mcp.pubfi.ai/, 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 PubFi MCP server?
PubFi MCP is listed in the public MCP registry as ai.pubfi/mcp. Use MCP 2026-07-28 discovery or 2025-11-25 initialize to list and execute PubFi routes. This page covers its hosted endpoint (https://mcp.pubfi.ai).
Is the PubFi MCP server safe to use?
PubFi MCP scores 92 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 PubFi MCP server expose?
PubFi MCP exposes 4 tools: pubfi.capabilities.list, pubfi.capabilities.get, pubfi.route.execute, pubfi.substrate.runtime_upgrade.verify. Their descriptions and schemas cost roughly 484 tokens of context every time the server is loaded.
Does the PubFi MCP server require authentication?
Yes. PubFi MCP asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.
Is the PubFi MCP server still maintained?
PubFi MCP 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.
