{"slug": "tools-changed-senzing-mcp-remote", "title": "Tools changed: Senzing MCP (remote)", "summary": "Senzing's remote MCP server at https://mcp.senzing.com/mcp scored 90/100 in a five-test review, completing an MCP initialize handshake (protocol 2025-06-18, server sz-mcp-coworker 1.42.5) and listing 13 tools without credentials on 2026-11-01. The review recorded 2 of 2 read-only tool calls passing on the live endpoint, including get_capabilities and explain_error_code, with the 13 tools estimated at roughly 9,436 tokens under cl100k_base. The server's source is not public — github.com/Senzing/mcp holds only docs and the registry manifest under an All rights reserved license, which scored 0 on the license test — and the reviewer noted that tool calls may still require a key.", "body_md": "# Senzing MCP (remote)\n\n**90**/100\n\nScore = points from our five tests (install, handshake, maintenance, docs, license).

Initialize and tools/list worked with no sign-in (13 tools, server sz-mcp-coworker 1.42.5), and 2 of 2 real read-only tool calls passed. The source still isn't public, which stays a caveat. On 2026-11-10 the 65 cap was lifted because the endpoint is on a product domain the vendor owns and real tool calls passed, so the score is 90.\n\nTool-call test (2026-11-01, direct MCP stdio client, no LLM): **pass**. 2 of 2 read-only calls passed on the live endpoint: get_capabilities described the server and its 13 tools; explain_error_code explained SENZ0002. No credentials. Evidence: live endpoint probe, Nov 1, 2026.\n\nSenzing-hosted public endpoint, no sign-in.
