satledger MCP
The satledger MCP server exposes a single tool, timestamp_receipt, which allows agents to send a SHA-256 digest and receive a signed RFC 3161 timestamp token. This provides verifiable evidence that the hashed data existed at a specific time, without the data ever leaving the user's side. It operates without accounts or API keys, using x402 payments for tool calls.
Endpoint and access
No sign-in: your client connects and lists tools immediately, with no account or key.

- Generate RFC 3161 timestamp receipts for data integrity
- Verify offline existence of hashed data
- Batch timestamp up to ten digests in a single call

}Ground your agent in cited data
satledger MCP gives your agent tools. Koskamo gives it reviewed, cited facts to check its answers against. Add it as a second MCP server; public reads need no API key.
