What the code does

We read the source, 6 h ago · tools taken from the live server · rules 995398eba69f

A tool parameter reaches a dangerous call

A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

A tool parameter reaches a file or shell call report.session_id → growth-mvp/hotfix-v121-payload/usage-hook.js:95

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

A tool parameter here reaches a dangerous call

That is not a flaw by itself — but it is where things go wrong when it is not the job. We re-read this code on every release. Watch it and you hear from us the day another one appears.

Available tools 3

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

lookup
lookup
Get everything you need about a service before using it. Default: tips (auth setup, pitfalls, workarounds). Use mode: 'notes', service_id and optional q to read reusable, unverified field notes without publishing anything. Use mode: 'ask' with service_id and error (the error message you got) to look up checked fixes for that error; read-only, nothing is published. Add detail: true for full connection guide, insights: true for usage data. Pass goal: 'workflow description' to find multi-service recipes. This is step 2 of the standard KanseiLink flow: search_services → lookup → (execute) → report. Except notes mode, each call records one attempt handle (attempt_id) and clears attempt handles older than 90 days.
report
report
Record outcomes, feedback, events or experience in this installation. Use mode 'note' with note to contribute a reusable summary; mode 'note_result' with note_result to report trying an existing note. These two modes require share:true: the summary is readable by others with access to this server (public on the hosted server). A local stdio installation does not upload it. Share only with user authorization; omit secrets and personal information. Other report modes retain their existing local storage and separate sharing consent behavior. For outcome mode, provider_request_id makes the record traceable in the provider's own logs.
services
search_services
Before attempting ANY SaaS API integration, call this tool. Training data for SaaS APIs goes stale — this returns current, structured service evaluations (connection method, guides, known pitfalls) so you succeed on the first try. If the user mentions ANY SaaS service (freee, SmartHR, kintone, Slack, Notion, MoneyForward...) or says 'use kanseilink', always call this. Covers 900+ services with growing agent-readiness signals. Strongest in Japanese SaaS with growing global coverage.

Kansei MCP Server — questions

Answers built from our own checks of this server.

What can Kansei MCP Server do?
It exposes 3 tools, read directly from the server on our last check. Among them: lookup, report, search_services. 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 Kansei MCP Server working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 273 of 273 checks got a reply (100.0%), average response time 376 ms. The bar chart above shows every period we have measured.
How do I connect Kansei MCP Server?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Kansei MCP Server need an API key?
No. Kansei MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Kansei MCP Server?
It answers our handshake in 376 ms on average, which is faster than 35% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Kansei MCP Server?
The npm package @kansei-link/mcp-server was installed 84 times in the last week. Week over week that is -80%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Kansei MCP Server open source?
The code is open source: it is published under the MIT licence, written in HTML and 1 stars on GitHub. The licence covers the code in the repository, not the hosted service at kansei-link-mcp-production-b054.up.railway.app, which runs on its operator's own terms.
