Paid SALT19 tools use governed semantic idempotency. Generate one _salt19_operation_id per intended purchase, preserve it across the unpaid challenge and every retry, add _x402_payment_signature after satisfying the challenge, and never create a fresh operation ID merely because the prior outcome is ambiguous. Standard x402 clients may omit _salt19_operation_id on the initial challenge and paid retry; SALT19 derives a compatibility operation identity from the payment proof and canonical purchase. An explicit _salt19_operation_id is recommended for the strongest semantic at-most-once timeout…

last good check
of 26 tools
The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

Discover and route to SALT19's url-to-llm-markdown capability. Fetch a public web page, remove scripts/styles/navigation noise, and return bounded LLM-friendly Markdown plus canonical URL and fetch provenance.
route-npm-package-facts unknown never probed
Discover and route to SALT19's npm-package-facts capability. Return live npm registry facts for the latest or requested package version without the higher-priced vulnerability and adoption decision layer.
route-github-repo-facts unknown never probed
Discover and route to SALT19's github-repo-facts capability. Return current public GitHub repository facts such as archive state, license, stars, forks, branch and latest push without the premium adoption decision.
route-agent-code-change-risk-gate unknown never probed
Discover and route to SALT19's agent-code-change-risk-gate capability. Static pre-merge risk gate for autonomous code changes: inspect a supplied unified diff for security-sensitive surfaces, destructive operations, architecture/constraint conflicts, test requirements, rollback risk, and bounded breaking-change risk before an agent merges or deploys.
route-agent-decision-preflight unknown never probed
Discover and route to SALT19's agent-decision-preflight capability. Before an autonomous coding agent installs or adopts software, return a bounded GO, WARN, or BLOCK decision with evidence and a portable SALT19 verification receipt.
route-github-repo-preflight unknown never probed
Discover and route to SALT19's github-repo-preflight capability. GitHub repository due diligence for coding agents: evaluate whether a public or open-source repository is safe and maintained enough to adopt using license, maintenance, release freshness, activity, project health, and risk signals.
route-model-memory-fit unknown never probed
Discover and route to SALT19's model-memory-fit capability. Can this AI model run on my graphics card? Estimate model memory requirements and check whether a quantized LLM fits available GPU VRAM before loading or local inference.
route-npm-package-intel unknown never probed
Discover and route to SALT19's npm-package-intel capability. Check whether an npm package is deprecated or vulnerable before installing it, including vulnerabilities, license, maintenance, freshness, dependency health, and package.json risk signals.
route-url-http-preflight unknown never probed
Discover and route to SALT19's url-http-preflight capability. Inspect a URL before an autonomous agent calls it, and preflight or verify a website or external API endpoint is healthy and safe to call by checking HTTP status, redirects, latency, and security headers.
route-agent-plan-verifier unknown never probed
Discover and route to SALT19's agent-plan-verifier capability. Verify an autonomous agent plan before execution for missing preconditions, destructive steps, unsafe ordering, goal misalignment, constraint violations, and repair actions, returning a bounded GO/WARN/BLOCK result.
route-dependency-go-no-go unknown never probed
Discover and route to SALT19's dependency-go-no-go capability. Dependency approval decision for coding agents: decide whether an npm dependency or package is safe to install or adopt and return GO, WARN, or BLOCK using vulnerabilities, security, license, maintenance, deprecation, and package metadata.
route-agent-claim-output-verifier unknown never probed
Discover and route to SALT19's agent-claim-output-verifier capability. Map an autonomous agent claim or output to supplied evidence and return SUPPORTED, PARTIALLY_SUPPORTED, NOT_PROVEN, or CONTRADICTED with explicit unsupported elements, contradictions, missing evidence, and recommended verification.

Discover and route to SALT19's repo-adoption-go-no-go capability. Repository adoption decision for autonomous coding agents using public GitHub maintenance, archive, license, and repository-health evidence, with explicit UNKNOWN and NOT_PROVEN boundaries for dependency, security, compatibility, integration, and project-fit claims.
route-dependency-upgrade-go-no-go unknown never probed
Discover and route to SALT19's dependency-upgrade-go-no-go capability.

route-commerce-decision unknown never probed
Discover and route to SALT19's commerce-decision capability. Before an autonomous agent pays an x402 challenge, bind the request, accepted payment offer, and machine spending policy into a deterministic GO/WARN/BLOCK decision with SHA-256 commitments.
route-commerce-receipt unknown never probed
Discover and route to SALT19's commerce-receipt capability. Verify an x402 commercial state and persist a signed Ed25519 Proof402 receipt whose Commerce State Root commits request, offer, policy, payment, settlement, and delivery evidence; receipts are later Merkle-batched for public inclusion proofs.
route-commerce-verify unknown never probed
Discover and route to SALT19's commerce-verify capability. Verify that an x402 v2 payment payload, settlement evidence, original request, accepted offer, spending policy, and delivered response are mutually bound; SALT19 operations can additionally be checked against authoritative D1 commercial state.
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
