search

Real-time web search - up to 10 results with title, URL, a cleaned page extract and publish date when available, plus an optional short summary.

Potential side effects

translate

Translate up to 200 text segments in a single call - the same result that would otherwise take 200 separate calls to translate a whole file.

Inferred read-only

jobs

Multi-query web research, read and synthesized into one sourced JSON brief in a single call - what would otherwise cost an agent twenty calls and its whole context window.

Name: Kairos Relationship Memory
Version: 4.0.3

Capabilities

Server instructions

Free MCP surface for portable agent relationship memory cards (v1). Remember interlocutors, not isolated messages: who, channel, topics, what you learned, unanswered outreach. The server does not hold your memory — relationship_memory.store validates and returns a normalized card for you to persist locally; relationship_memory.retrieve returns schema, sample and optional starter card; relationship_memory.validate checks a card only. HTTP mirror: https://x402.agentindex.world/relationship-memory/. Schema: https://x402.agentindex.world/.well-known/relationship-memory.json

Known tools 3

relationship_memory.validate

Validate a relationship memory card against the v1 JSON Schema — free.

Inferred read-only

relationship_memory.store

Validate then return a normalized card ready to persist on the caller side — free, stateless (no server-side database).

Inferred read-only

relationship_memory.retrieve

Return schema, sample, HTTP and MCP entrypoints.
