Overview

Description from the maker (original English)

RFC 3161 timestamps with no account, and a signed agent-ledger workspace. Paid per call over x402.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • timestamp_receipt

    Submit a SHA-256 digest and receive a Time-Stamp Authority's signed RFC 3161 token over it: evidence that the data you hashed existed at that time, verifiable against the authority without trusting or contacting this service. Hash your data yourself - it never leaves your side. Y

  • provision_workspace

    Buy a workspace: a tamper-evident usage and action ledger for your agents, every event ed25519-signed and hash-chained, with an export your own customers verify offline. Pay over x402 in _meta[x402/payment]: 0.50 USDC for 2,500 units (starter), 15.00 USDC for 100,000 units (block

  • top_up_workspace

    Add units to a workspace you already hold. Send its API key in _meta[satledger/api-key] (or the api_key argument) and the payment in _meta[x402/payment]: 0.50 USDC for 2,500 units (starter), 15.00 USDC for 100,000 units (block). The units land in that workspace and nothing new is

  • create_agent

    Create an agent in your workspace: a named ledger whose every event is ed25519-signed and hash-chained. `initial_credits` mints supply to the workspace issuer, not to the agent - fund_agent moves credits across when you need usage metering. Costs 1 unit. Authenticate with the wor

  • record_action

    Append what an agent did - a tool call, a decision, a message - as a signed, hash-chained entry. This is the thing the workspace is for. Costs 1 unit. Authenticate with the workspace key in _meta[satledger/api-key].

  • fund_agent

    Move credits from the workspace issuer to an agent's own account, so record_usage can burn them. Costs 1 unit. Authenticate with the workspace key in _meta[satledger/api-key].

  • record_usage

    Burn credits from an agent's account, as a signed ledger event. Costs 1 unit. Authenticate with the workspace key in _meta[satledger/api-key].

  • anchor_agent

    Ask a public RFC 3161 Time-Stamp Authority to sign the agent's current state. The one fact here the operator cannot manufacture: a timestamp cannot be issued for a time that has passed. An unchanged state returns the anchor it already has. Costs 100 units. Authenticate with the w

  • export_agent

    Build the export bundle, run the customer-side verifier over it and return the summary plus the URL of the archive (HTTP, X-API-Key, free). Pass expect_action_head / expect_action_count from state YOU kept to check completeness. Free, permanently. Authenticate with the workspace

  • list_agents

    Every agent in your workspace. Free. Authenticate with the workspace key in _meta[satledger/api-key].

  • describe_agent

    Current state: root id, state hash, event count, balance. Free. Authenticate with the workspace key in _meta[satledger/api-key].

  • list_actions

    The agent's action log, with its head hash. Free. Authenticate with the workspace key in _meta[satledger/api-key].

  • list_anchors

    Every anchor commitment recorded for the agent. Free. Authenticate with the workspace key in _meta[satledger/api-key].

  • workspace_balance

    Units remaining and what each operation costs. Free, so you can plan before you are refused. Authenticate with the workspace key in _meta[satledger/api-key].

Common questions

Is satledger timestamp receipt safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.21.4) reached the registry 11 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?
