Available tools 16

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

swarm

run_swarm_research

Run the swarm Agency: compose a research product and list it for resale. Spends nothing by default — the report is synthesized from free inputs, so unsold inventory costs nothing. Pass allow_paid_inputs=True to buy upstream x402 services first (buy → compose → list), which books a cost basis before knowing whether the composite will sell.

swarm_revenue_report

Portfolio revenue intelligence for the swarm: spend, revenue, LTV:CAC, margins, per-source profit scores.

activate

activate_pro_tier

Verify pro-tier x402 payment and unlock Pro quota limits.

base

get_base_pulse

Live Base Network Pulse: synthesized settlement-conditions intelligence (base fee, EIP-1559 projection, utilization trend, USD settlement cost, and a settle-now/hold verdict) computed from real Base RPC data + ETH spot price.

build

build_seller_requirements

Build seller-side x402 payment requirements via x402ResourceServer. Pass resource_url (plus optional discovery_* fields) to embed the Bazaar discovery extension so a settled payment catalogs the endpoint.

discover

discover_services

Discover x402 Bazaar paid HTTP services via x402 HTTPFacilitatorClient.

metrics

get_os_metrics

Host OS telemetry: CPU, memory, swap, disk, network, and process signals with an ok/warn/critical health verdict, sampled live from the machine running the server. Optionally includes the top processes by memory.

pay

pay_and_fetch

Pay via x402HttpxClient and fetch a protected HTTP resource.

payment

get_payment_requirements

Probe a URL for x402 payment requirements using x402HTTPClient SDK.

pro

get_pro_upgrade_requirements

Build x402 payment requirements to purchase Pro tier (revenue collection).

purchase

purchase_tool_credits

Verify x402 payment and add per-use tool credits (per-call revenue path).

settle

settle_composite_sale

Verify + settle a buyer's x402 payment for a listed composite product and record the realized revenue (sell side).

stripe

create_stripe_checkout

Create Stripe Checkout Session for pro tier or tool credits (fiat rail).

supported

get_supported_networks

List networks, facilitators, and v2 headers via x402 SDK.

tool

get_tool_credits_requirements

Build x402 payment requirements to purchase per-use MCP tool credits.

verify

verify_payment_payload

Verify PAYMENT-SIGNATURE via x402ResourceServer + facilitator.

X402 MCP — questions

Answers built from our own checks of this server.

What can X402 MCP do?

It exposes 16 tools, read directly from the server on our last check. Among them: activate_pro_tier, build_seller_requirements, create_stripe_checkout, discover_services, get_base_pulse, get_os_metrics and 10 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is X402 MCP working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 556 ms. The bar chart above shows every period we have measured.

How do I connect X402 MCP?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does X402 MCP need an API key?

No. X402 MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 16 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is X402 MCP?

It answers our handshake in 556 ms on average, which is faster than 19% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is X402 MCP open source?

Yes — written in Python, 2 stars on GitHub and 5 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
