Yes. Skim is open source under the MIT license; the repository is https://github.com/JessieJanie/skim402. Checked as of 2026-11-09.

Which chains does Skim support?

Skim lists support for Base as of 2026-11-09.

Is Skim still maintained?

The most recent code activity Sato Hub observed was on 2026-11-01 (last commit 2026-11-01, last release 2026-06-13), which Sato Hub labels "Active". Posts on X are not counted as maintenance. Activity is a recency signal, not a quality judgment.

How do I install or run Skim?

Node.js >=18. Install: npx -y skim-mcp. Entry: {"mcpServers":{"skim":{"command":"npx","args":["-y","skim-mcp"],"env":{"SKIM_API_KEY":"sk402_..."}}}}. Sato Hub reproduced this install in a container on 2026-11-02. It runs as an MCP server (npx -y skim-mcp (stdio)).

Is Skim verified on Sato Hub?

Sato Hub holds one earned check for Skim: Deploy path reproduced — install verified in an isolated container (proves installability, not runtime safety). Its Sato Score is 89 of 100, a measure of how open, active and verifiable the project is, not a safety, quality or returns grade.

Overview

https://skim402.com answered on 2026-09-23 (page title: "Skim — a clean URL-to-markdown reader for agents"). Source is public at JessieJanie/skim402 (MIT, 2★); created 2026-05-19, last pushed 2026-08-31. Documentation at https://skim402.com/docs answered on 2026-09-23. An MCP initialize handshake against https://skim402.com/mcp completed on 2026-09-23 and listed 3 tools. One unpaid request to https://skim402.com/api/v2/read answered HTTP 402 with a payment payload we could parse (network eip155:8453, asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). No payment was sent: a 402 says the endpoint asked for money in a readable shape, not that paying works or that the seller delivers. The host serves an x402 capability manifest at /.well-known/x402. Listed from a maintainer submission; every field is self-reported except the checks above, which Sato Hub ran itself on 2026-09-23.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

A local server: your client runs this command on your machine. Installing runs third-party software under your own credentials. Sato Hub publishes the documented invocation and, where the harness reproduced it, the date it did — neither is a safety review.

Answers a call: not asked — no tool is named as a read (list_/get_/search_)

Live probe verifies the interface responds — not what the tools do, their safety, or their output quality. The call is one read-only tool named by this server's own list (list_/get_/search_, no mutating verb anywhere in the name, no required arguments and none that look like a key, an address or an amount), asked once a day with no arguments. Not asked is not a failure.

Succeeded: 48
Failed: 0
Their error: 0
Unattributed: 0

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden.
