A remote MCP server that gives an assistant read-only telemetry on the x402 machine-payment economy: catalogue changes, provider shortlists, market totals and a
What you can do
Track daily changes in the x402 Bazaar catalogue: listings added, removed and repriced, with totals from full-catalogue snapshots diffed by resource URL. Find x402 endpoints worth calling, ranked by reported paying buyers, call volume, days listed and price stability, returned as a positive-only shortlist. Read ecosystem-wide x402 totals from a daily market scan alongside one shop's live challenge, payment and revenue counters. Review a running scoreboard of an autonomous agent's pre-registered market hypotheses, with verdicts and measured values. See which networks and countries are crawling a live paid endpoint, with daily challenge, paid-call and self-test totals.
When to use it
Useful when you want an assistant to survey the x402 paid-endpoint ecosystem, compare candidate providers, or follow an autonomous market experiment and its scored hypotheses without building your own snapshot pipeline.
Requirements
A remote streamable HTTP endpoint; no packages, environment variables or headers are declared, and no authentication is declared. Network access to the remote endpoint is required.
Before you install
All five tools are read-only reporting; no writes, payments or credentials are requested. Figures mix third-party catalogue data with the operator's own shop telemetry, so treat the market and scoreboard numbers as one experiment's published claims rather than independent verification.
Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/observer.remote%2Fremote-observer/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.
What changed in the x402 Bazaar catalogue in the last day — listings added, removed and repriced, with catalogue totals. Computed from full-catalogue snapshots taken daily since July 2026 and diffed by resource URL, so every count is of real rows, not an estimate.
Takes no parameters.
find_provider
Find x402 endpoints worth calling — ranked by the catalogue's own reported paying buyers and call volume, how many days they have stayed listed and whether their price held. Built from 30 days of daily catalogue snapshots and returned as a positive-only shortlist: absence is missing evidence, never a bad review.
Parameterslimitquery
market_stats
Ecosystem-wide x402 totals from the daily market scan, next to the live challenge, payment and revenue counters of one shop that actually runs paid endpoints and publishes what they earn. The market figures come from that scan; the shop figures are our own endpoints' meter, published as one seller's instrument — self-test settlements counted and published separately, never folded into the paid figure.
Takes no parameters.
experiment_scoreboard
The running scoreboard of an autonomous agent's market hypotheses — each claim, its target, its verdict, the value actually measured, and the creative lens (or control) it was drawn under. Every hypothesis is pre-registered before the evidence exists and scored by code on a fixed horizon, with refutations published exactly like confirmations.
Takes no parameters.
crawler_watch
Who is actually crawling the x402 economy — the top networks and countries behind payment challenges on a live paid endpoint, with that day's challenge, paid-call and disclosed self-test totals. Straight from one shop's edge telemetry, where measured new-listing pickup latency runs about 45 minutes, self-tests are counted apart from paid calls rather than netted out of them, and the traffic is indexers reading prices, not buyers.
Takes no parameters.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
