Point your MCP client at this streamable-http endpoint: https://fudousan-mcp.easakura.workers.dev/mcp
The endpoint did not complete an MCP handshake.
Check the URL, TLS certificate and that the server answers a JSON-RPC "initialize" POST. How to fix →
3 of 3 tool(s) carry no readOnlyHint/destructiveHint annotations.
Annotate read-only tools with {"readOnlyHint": true}. Agents and gateways can then run them without a confirmation prompt, and route around destructive ones. How to fix →
Handshake + tools/list takes ~2,172 ms.
Serve tools/list from memory, keep the process warm, and host close to your users. Every new agent session pays this before its first call.
No tool declares an outputSchema.
Declare outputSchema and return structuredContent (MCP 2025-06-18+). Agents can then parse results without guessing, and chain tools reliably. How to fix →
Paste-ready definitions with the problems above fixed. Changes marked verify need a human look. All of them as JSON: /v1/readiness/mcp-registry%2Fio.github.easakura%2Fjapan-real-estate-mcp/fixes

As of 2026-10-13 03:47 UTC, the Easakura Japan Real Estate MCP server is unknown with a Glimind reliability score of 51/100 (grade D). Over the last 30 days it answered 0% of Glimind's liveness checks. It had 1 outage in 90 days, with a median recovery of 2 minutes.
Easakura Japan Real Estate MCP server advertises 3 tools, including get_land_price, list_municipalities, search_transactions.
Point your MCP client at this streamable-http endpoint: https://fudousan-mcp.easakura.workers.dev/mcp
Glimind scanned all 3 tool definitions for tool-poisoning patterns — hidden or invisible characters, instructions that override the model, concealment from the user, requests to read credential or MCP config files, conversation exfiltration and cross-tool shadowing — and found none. This checks what the server tells the model, not what its code does; review the source before granting access to sensitive data.

Status is an automated estimate from Glimind's liveness checks (handshake and tool listing only; no tool is ever called) and may lag or differ from your network. Glimind is not affiliated with this server or its operator. Operator? Request a correction or opt out at https://glimind.com/opt-out.
