The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
check_x402_endpoint Check an x402 endpoint before paying ~75
Before paying an unknown x402 endpoint, check whether it is live and returns a valid x402 payment challenge. Returns liveness, price, network and a pay/avoid verdict. For full uptime + reputation, use PulseFeed's paid /trust API.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | The x402 endpoint URL to verify |
No output schema declared.
No examples provided.
mcp_check_server Audit an MCP server before installing ~83
Before installing an MCP server, audit it by npm package name: does it run an install script (arbitrary code at npm i), is it abandoned, does it ship a repository/license, weekly downloads, provenance — verdict safe/caution/avoid. Free.
| Name | Type | Req | Description |
|---|---|---|---|
| package | string | yes | npm package name of the MCP server, e.g. @scope/name |
No output schema declared.
No examples provided.
mcp_drift_check Has an MCP package changed since you trusted it? ~162
The rug pull check. `mcp_check_server` answers whether a package is safe TODAY; this answers what CHANGED after it was adopted: an install script added in a later version (arbitrary code on `npm i` that was not there at review time), package ownership swapped, repository removed, package unpublished, build provenance lost. Pass your own dependency list to check it in one call. Derived from a daily external re-audit of the whole MCP package population — an event exists only because a snapshot from before it exists. Free.
| Name | Type | Req | Description |
|---|---|---|---|
| days | integer | – | Window in days (default 30) |
| packages | array | – | npm package names to check, e.g. your installed MCP servers. Omit for the whole ecosystem feed. |
No output schema declared.
No examples provided.
mcp_security_report State of MCP security ~68
State of MCP Security: how many audited MCP servers run an arbitrary install script on npm i, are abandoned, ship no repository or license — with day-over-day deltas and a sample of currently-flagged servers. From PulseFeed's daily MCP audit (950+ servers). Free.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
pulsefeed_products PulseFeed products and pricing ~57
List PulseFeed's paid x402 products — real-time Base on-chain intelligence for AI agents: token pulse, whale alerts, smart-money accumulation/distribution, momentum, and the x402 trust oracle — and how to pay via x402.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
x402_changes Recent x402 ecosystem changes ~82
What changed in the x402 ecosystem in the last 7 days: services that went dark, receiver (payTo) swaps — possible hijacks, price changes, recovered and newly-seen services. Derived from PulseFeed's compounding time-series (cannot be reconstructed after the fact). Free.
| Name | Type | Req | Description |
|---|---|---|---|
| days | integer | – | Window in days (default 7) |
No output schema declared.
No examples provided.
x402_data_sample Free sample of the trust dataset ~80

Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
x402_ecosystem_stats x402 ecosystem health stats ~68

Input schema present but exposes no named parameters.
No output schema declared.

|---|---|---|---|
| days | integer | – | Window in days (default 30) |

x402_working_services List live x402 services ~70
List x402 agent-payment services that are currently ALIVE and return a valid x402 challenge, ranked by trust score. A large share of listed x402 endpoints are dead or invalid (live figure at pulsefeed.dev/status.json) — use this to avoid paying broken or scam endpoints. Free.
