Continuous observation
Servers and endpoints are actively called rather than merely listed. Answering, silence, latency, and protocol behavior stay visible.
Independent reliability intelligence for the agent economy
What answers when
an agent calls.
MCP Scores continuously probes MCP servers and x402 endpoints, preserves the evidence, and publishes a verifiable record of what actually works.

The public reliability layer for agent infrastructure.
Directories tell people what exists. MCP Scores records what actually responds, what it exposes, what payment terms it declares, and which evidence supports the claim.
Preserved evidence
Responses, tool inventories, payment terms, observed states, and collection dates remain attached to the public record.
Verifiable scorecards
Every published result resolves to an inspectable scorecard. Below the evidence floor, the only honest result is NR.
Agent-native access
The website, API, live badge, and MCP tools all read the same underlying computation and evidence.

4,344 researched listings · latest sweep 2026-08-12
Accessible summary: 4,344 researched listings, each shown at its own latest observation. 2,130 answered when they were last called, 1,959 were silent, and 255 have never been probed. Most recent sweep Aug 12, 2026 UTC re-called 2,752 of them; 1,337 were last called earlier. The linked registry provides each listing as text.

From discovery to a defensible public record.
The pipeline separates collection from publication. A listing can exist in the registry long before the evidence supports a grade.
Discover
Registry and catalogue sweeps identify MCP servers and x402 endpoint hosts.
Probe
Unpaid calls test reachability, protocol responses, latency, and available tool surfaces.
Preserve evidence
Observed states, response facts, metadata, payment terms, and dates enter the archive.
Publish when supported
A grade appears only after both the archive and successful-observation thresholds are met.
Public evidence, listing by listing.
A concise view of identity, observed state, tool surface, payment evidence, and rating status. Blank evidence is never rewritten as zero.

Live badge · API · MCP
One computation, wherever the decision is made.
The badge is free, served live, and linked to evidence. The public API and MCP tools expose the same status with no account or paid data tier.

The evidence floor is a feature
We do not publish a number before the evidence supports one.
NR is intentional. It means the archive has not yet met both the 7-day coverage floor and the 3-successful-observation floor. It is neither a favorable nor an adverse finding.
Evidence-based
Every measured input cites its source table and the date it was observed.
Publicly inspectable
Each scorecard exposes the full evidence ledger and the limitations that apply to it.
Consistent everywhere
Website, API, badge, and MCP tools all call one computation — there is no second number.
