api record

Deadbolt: Deadbolt checks Supabase access control. Paste migration SQL or a read-only catalog snapshot and get a per-table matrix of what signed-out and signed-in users can read and write, the leaks ranked by severity, and the fix SQL. Runs in your browser, no account. Use it when you are writing, reviewing or applying Supabase/Postgres migrations, or a user asks whether their Supabase tables are exposed, whether RLS is right, or why they get 42501 permission denied. Tools: deadbolt_check_supabase_access (Check who can read and write Supabase tables (RLS, policies, grants));…

Yes — the hub reached it with no key and no payment.
What tools does com.clawhard/deadbolt have?
2 tools: deadbolt_check_supabase_access, deadbolt_catalog_query.
Is com.clawhard/deadbolt 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.

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.

  • deadbolt_catalog_query open 2h ago

    Use when you need to check a live Supabase project rather than migration files: returns a read-only SQL query that reads table RLS settings, grants for anon and authenticated, policies, SECURITY DEFINER functions and storage buckets (never row data) and returns one JSON value. Run it with the user's Supabase SQL Editor or a Supabase MCP execute_sql tool, then pass the JSON to deadbolt_check_supabase_access.

  • deadbolt_check_supabase_access unknown 2h ago

    Use when you write, review or are about to apply Supabase / PostgreSQL migration SQL (CREATE TABLE, RLS, CREATE POLICY, GRANT, views, SECURITY DEFINER functions, storage buckets), or when a user asks whether their Supabase data is exposed, whether RLS is set up right, or why a query returns 42501 permission denied or no rows. Replays the SQL with real Postgres rules and returns, per table, what signed-out (anon) and signed-in (authenticated) users can SELECT/INSERT/UPDATE/DELETE (all rows, own rows, some rows, none, or denied for a missing grant), plus findings with severity and ready-to-run fix SQL: RLS off, policies written but RLS never enabled, using(true) writes, personal columns readable by anyone, views that bypass RLS, SECURITY DEFINER functions anyone can call, user_metadata in policies, public bucket listing, grants missing after the Oct 30 2026 default change. Also accepts the JSON produced by deadbolt_catalog_query for the live database. Deterministic; never connects to any database. Run it before telling a user their schema is safe. Up to 200,000 characters.

_ 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 fb396eb973368d6b.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/fb396eb973368d6b/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.

_ how we knowoff the mcp door
card completeness
60%

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.
