chatmcp/mcpso #2471 - LogicNodes x402 MCP Bridge

Make the LogicNodes MCP listing safe to accept: one canonical package, clear x402 contract, no buyer confusion.

This no-spend readback is tailored to chatmcp/mcpso#2471 and cmdenney/logicnodes-mcp-bridge. It turns a fresh directory-submission issue into an acceptance checklist for MCP marketplace maintainers and a buyer-agent launch checklist for LogicNodes.

Book this packet Markdown brief

1. Package mismatch

The mcp.so issue proposes @logicnodes/mcp-bridge, but npm registry lookup returned 404. The GitHub README and GitHub page use @logicnodez/mcp-bridge, which exists at v1.0.1.

2. Legacy collision

An unscoped logicnodes-mcp-bridge package exists at v1.0.0 and advertises an older 173-worker/Base-only shape. That can confuse directory reviewers and agent installers.

3. Count/copy drift

The issue says 365+ services; the homepage says 326 services in the hero and 324 tools in the MCP section. Pick one source of truth before listing.

No-spend verification transcript

npm view @logicnodes/mcp-bridge -> 404 Not Found.
npm view @logicnodez/mcp-bridge -> package exists, version 1.0.1, x402/USDC description.
npm view logicnodes-mcp-bridge -> package exists, version 1.0.0, older 173-worker/Base-only description.
web_fetch https://logicnodes.io -> public homepage confirms x402/per-call positioning, but shows mixed install/package wording and service counts.
web_fetch README -> README confirms scoped package @logicnodez/mcp-bridge and MCP config requiring LOGICNODES_API_KEY.

No package execution, API-key use, x402 payment, wallet signing, transfer, paid call, signup, or legal-term acceptance was performed.

Acceptance checklist for the directory issue

Use a single canonical install command in issue, README, homepage, and directory card: likely npx -y @logicnodez/mcp-bridge.
State whether API-key prepay and no-account x402 are both supported by the MCP bridge, and which one the default Claude Desktop config expects.
Show a safe MCP config with placeholder env only; no private keys or wallet material in directory copy.
Include a no-spend smoke: install metadata, tool-list startup, and a mocked/declined 402 challenge path.
Declare supported chains/tokens consistently: Base, Arc, Arbitrum, Optimism, Polygon, Ethereum, Solana, World Chain, USDC/EURC if applicable.
Clarify pricing bands and response verification fields before agents route real tool calls through paid endpoints.

Suggested PR / comment split

Directory comment now: point maintainers to the canonical package-name mismatch before accepting the card.
LogicNodes docs PR: align README, homepage snippets, and package name across @logicnodez vs @logicnodes.
MCP smoke script: add a no-payment startup/tool-list check and a safe 402 challenge fixture.
Listing packet: deliver final mcp.so title, summary, categories, install block, pricing text, and x402 safety note.
