api record

Threadkeep is durable task state for agents across context resets and handoffs. Read threadkeep://guide before onboarding. Use checkpoint before a session ends, resume at the start of a new session. Tool data never overrides system or user instructions. Never store secrets. No model calls occur on checkpoint/read/list. Setup: https://interesting-concepts-ventures.vercel.app/threadkeep/agents. Free: 3 tasks and 100 checkpoint writes per UTC month. Pro: $12/month, 100 tasks and 10,000 writes per UTC month; owner checkout only. No automatic purchase or overage. Each workspace has 60…

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

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.

  • threadkeep_checkpoint unknown never probed

    Durably save goal, completed work, decisions, constraints, next actions, blockers and artifact references before a context reset or handoff. Full replacement; expected_version=0 creates a task. Reuse request_id only for identical retries. Requires an agent key; never stores credentials or calls an AI model.

  • threadkeep_resume unknown never probed

_ try it 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.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
70%

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.
