> **Deprecated**: this server is marked deprecated in the MCP registry. The registry records this reason: "Free MCP surface retired 2026-09-19 (discours-public cleanup, commit 242e309), tools were never remounted after a later refactor, so this endpoint has 404ed since. No replacement endpoint; do not retry."

## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-22.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not yet verified: we couldn't confirm whether this endpoint requires it.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but the endpoint returned HTTP 404.
- **Schema Quality & AI Usability**: 0/100
  - Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Tool Safety**: 0/100
  - Tool safety not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Capabilities**: 0/100
  - Capabilities not yet verified: we couldn't read the endpoint's capabilities.

**Unverified: 5 categories.** Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## Install

### How do I install the Kairos Relationship Memory MCP server?

Kairos Relationship Memory is a hosted endpoint at https://x402.agentindex.world/mcp/relationship-memory/, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

### What is the Kairos Relationship Memory MCP server?

Kairos Relationship Memory is an MCP server listed in the public MCP registry as io.github.agentindexworld/relationship-memory. Free MCP: relationship_memory validate, store (local), retrieve, portable interlocutor cards v1. This page covers its hosted endpoint (https://x402.agentindex.world/mcp/relationship-memory/).

### Is the Kairos Relationship Memory MCP server safe to use?

Kairos Relationship Memory scores 23 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Kairos Relationship Memory MCP server expose?

Kairos Relationship Memory exposes 3 tools: relationship_memory.validate, relationship_memory.store, relationship_memory.retrieve. Their descriptions and schemas cost roughly 116 tokens of context every time the server is loaded.

### Does the Kairos Relationship Memory MCP server require authentication?

Its publisher declares no required credentials for Kairos Relationship Memory. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

### Is the Kairos Relationship Memory MCP server still maintained?

Kairos Relationship Memory is marked deprecated in the MCP registry. We last reached this channel on 22 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
