api record

Pacta by Fractal Neurons: 6 read-only, block-pinned pre-execution inspection tools for EVM contracts (Ethereum, Base) + 1 opt-in request tool. If you only have a protocol or token name (e.g. 'Aave', 'Ethena', 'USDe', 'Moonwell', 'kUSD'), call pacta_lookup_protocol first to resolve its verified record and checksummed 0x contract address, then call pacta_check_preflight. Call pacta_check_preflight before an agent approves, deposits into or calls a contract: it says who can change it (EOA, Safe, timelock, nobody), how fast, and whether it can pause, blacklist or upgrade. pacta_scan_control_plane…

_ is it live, free and safe measured by this hub
Is pacta-mcp-remote live?
Yes — it answered the hub's last check (checked 38m ago). It answered 100% of checks over the last 30 days.
Is pacta-mcp-remote free to use?
Yes — the hub reached it with no key and no payment.
What tools does pacta-mcp-remote have?
7 tools: pacta_scan_proposal_diff, pacta_scan_control_plane, pacta_scan_timelock_op, pacta_submit_request, pacta_check_preflight, pacta_get_live_timelocks, pacta_lookup_protocol.
Is pacta-mcp-remote safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 7 tools
7 never probed 0 of 7 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • pacta_scan_proposal_diff unknown never probed

    Re-runs the pinned contract reads of a Pacta-tracked governance proposal (Aave, Euler, Morpho, Sky) at the live block and returns pinned-vs-live diffs. Free during the launch (no key, no payment).

  • pacta_submit_request unknown never probed

    Opt-in: queue a coverage or feature request with Pacta when a target is not indexed, a chain or check is unsupported, or data looks wrong (coverage_gap_hint). Ask the user first. Free in every pricing mode, 5 per hour; an identical request_type + target_subject upvotes the existing request (same request_id). Returns request_id, status, demand_votes and an optional fast_track_url. Never opens a GitHub issue. Pass contact_handle ONLY when the user explicitly asks for follow-up or an invoice.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 4843e5059ef8e2d7.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/4843e5059ef8e2d7/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
