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 Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- 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 Usability88
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1305 tokens (~108/item across 12 items; 11 tools + 1 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 Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
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 11 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 13 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
- Supports UI / widget rendering.Pass
Unverified: 1 category
A category scored 0 because we could not verify it: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.
How do I install the Priors (hosted, read-only) MCP server?
Priors (hosted, read-only) is a hosted endpoint at https://mcp.priors.trade/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 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 →
agent_record Priors credit record of an agent ~109
Show a Priors agent's full credit record on Robinhood Chain: name, owner address, who backs it (its sponsor/backer), its credit line, what is drawn and available, loans repaid and volume, score, open loans with due dates, and whether it has defaulted or is frozen. Use it before trusting, paying or lending to an agent. Read-only.
| Name | Type | Req | Description |

credit_history Priors' ERC-8004 credit statements for an agent ~149
Show the loan history Priors posted for an agent on the ERC-8004 reputation registry (Robinhood Chain): loans repaid on time, repaid late and defaulted, and loans outstanding, from Priors' credit statements (the erc8004-credit/v1 profile). Each statement is read from its own transaction and checked here: its bytes and hash, the chain of statements, and a sample of its loans against the pools' logs. The totals are Priors' claims checked on that sample; the answer gives the command that rebuilds every loan. Read-only.
| Name | Type | Req | Description |

Call this when the user wants to pay, borrow, repay, or set Priors up. Read-only.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
pool_stats Priors pool figures ~70
Show the Priors credit pool's current figures: liquidity available to lend, principal out on loans, total assets, reserve, fees earned, bad debt, number of agents, open loans, all-time loans repaid, and the loan terms (fee, min/max loan, min/max term). Read-only.

What is the Priors (hosted, read-only) MCP server?
Priors (hosted, read-only) is an MCP server listed in the public MCP registry as io.github.priors-agents/priors-read. Credit records and scores of ERC-8004 AI agents on Robinhood Chain, from Priors. No key needed. This page covers its hosted endpoint (https://mcp.priors.trade/mcp).
Is the Priors (hosted, read-only) MCP server safe to use?
Priors (hosted, read-only) scores 76 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 Priors (hosted, read-only) MCP server expose?
Priors (hosted, read-only) exposes 17 tools: agent_record, score_of, credit_history, pool_stats, stock_assets, and 12 more. Their descriptions and schemas cost roughly 2,097 tokens of context every time the server is loaded.
Does the Priors (hosted, read-only) MCP server require authentication?
No. We connected to Priors (hosted, read-only) without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Priors (hosted, read-only) MCP server still maintained?
Priors (hosted, read-only) is still listed as active in the MCP registry. We last reached this channel on 4 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
