Quality: 60/100 (Good) | Auth: No auth required
MCP Orchestrator
Aggregators · Local stdio
Quality: 60/100 (Good) | Auth: No auth required
Verdict Summary: Choose Kansei MCP Server if you need specialized Aggregators tools running via a local process. Choose MCP Orchestrator if your workspace requires Aggregators integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Kansei MCP Server when:
You need dedicated capabilities in the Aggregators domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Before attempting ANY SaaS API integration, call this tool. Agents waste 3-5x more tokens on trial-and-error with stale training data — 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.
lookup
Get everything you need about a service before using it. Default: tips (auth setup, pitfalls, workarounds). 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.
report
Record what happened after using a service: success/failure outcome, feedback, API change events, or qualitative experience. Data is saved to this installation's LOCAL database only (improves local recovery hints and stats) — nothing is sent to KanseiLink unless you separately opt in to sharing. PII is auto-masked before storage. This is step 4 of the standard flow: search_services → lookup → (execute) → report.
MCP Orchestrator Tools (2)
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Kansei MCP Server is categorized under Aggregators and uses a local stdio subprocess. In contrast, MCP Orchestrator belongs to Aggregators using local stdio subprocess. Select Kansei MCP Server when you need capabilities focused on aggregators and MCP Orchestrator when you require tools for aggregators.
Search for tools using BM25 relevance ranking or regex pattern matching.
Searches across tool names, descriptions, and argument names/descriptions.
By default, uses BM25 natural language search. Set use_regex=True to search
using Python regex patterns instead.
Returns tool_reference blocks for discovered tools with deferred loading.
call_remote_tool
Call a tool directly on a registered remote MCP server through the orchestrator.
This tool allows direct invocation of any tool on a downstream MCP server.
The tool name should be in the format 'server_name__tool_name' (e.g., 'context7__query-docs').
