Witnessory client

Witnessory measures how far the internet has moved to post-quantum cryptography. This is the client: the services as Python functions, a command line, and an MCP server so an agent can use them as tools. Standard library only; Apache 2.0.

pip install https://github.com/witnessory/client/releases/download/v0.1.0/witnessory-0.1.0-py3-none-any.whl

From the command line

witnessory check example.org          # one site's post-quantum readiness, in a sentence
witnessory check example.org --json   # the whole signed result
witnessory headline                   # the observatory's headline figures, by layer
witnessory probes                     # where the probes measure from
witnessory status                     # whether every service is up
witnessory pricing                    # what is paid, and the prices

From Python

import witnessory
r = witnessory.check("example.org")
print(r["summary"])                   # "example.org: a current browser gets post-quantum key exchange ..."
witnessory.verify(r)                  # {"ed25519": True, "mldsa65": True}  (needs: pip install "witnessory[verify]")
witnessory.headline()["layers"]["keys"]

As an MCP server, for agents

Command witnessory, argument mcp. For example, in a client's configuration:

{"mcpServers": {"witnessory": {"command": "witnessory", "args": ["mcp"]}}}

Tools: check_site, pq_headline, probe_map, service_status, pricing. Resources: Witnessory's llms.txt and pricing.json. Messages are JSON-RPC, one per line, on stdin and stdout.

Limits and keys

A free check is one vantage, once: 20 new checks an hour from one address, results reused for 10 minutes. A paid plan's key (WITNESSORY_KEY, or --key) makes checks fresh and counted per month instead of per address. Every answer carries offers: what more there is and where the prices are (https://witnessory.org/pricing.json). Watching your own sites over time from several networks, with alerts and signed evidence, is a separate product on the same page.
