Persistent memory for AI agents. Give your coding assistant organizational context that compounds — search memories with hybrid retrieval, store anything with auto entity extraction, and query a living knowledge graph that gets smarter over time.

Overview

What is Crosmos?

Crosmos is a persistent memory layer for AI agents. Instead of starting every conversation from scratch, your agent can store and retrieve organizational knowledge across sessions — powered by a temporal knowledge graph with hybrid retrieval.

Tools

Tool	Description
`crosmos_search_memories`	Hybrid retrieval — semantic + keyword + graph traversal in one query
`crosmos_add_memory`	Store any content with automatic entity and relationship extraction
`crosmos_list_spaces`	List available memory spaces
`crosmos_health_check`	Verify API connectivity and status

Quick Start

npx @crosmos/crosmos-mcp setup

This auto-detects your installed MCP clients and configures everything. Get your API key at console.crosmos.dev.

Manual Config

{
  "mcpServers": {
    "crosmos-memory": {
      "command": "npx",
      "args": ["-y", "@crosmos/crosmos-mcp"],
      "env": {
        "CROSMOS_API_KEY": "csk_your_key_here"
      }
    }
  }
}

Supported Clients

Claude Desktop · Claude Code · Cursor · VS Code · Windsurf · opencode · Cline · Roo-Cline · Zed

Why Crosmos?

- Graph-native — memories are linked as entities and relationships, not just stored as flat vectors
- Temporal — every fact is timestamped; query your knowledge graph as it existed at any point in time
- Hybrid retrieval — four parallel signals (semantic, keyword, graph, temporal) fused into a single ranked result
- Auto-extraction — send raw text; Crosmos extracts structured facts, entities, and relationships automatically
- Multi-space — isolate memory by project, team, or agent with named spaces

Clockify Time Tracking

@tracegazer

clockify-mcp exposes the Clockify time-tracking API as Model Context Protocol tools so any MCP client (Claude Desktop, Cursor, etc.) can query and manage time-tracking data in natural language. Covers 18 domains: workspaces, users, groups, clients, projects, tasks, tags, time entries, reports (detailed/summary/weekly/attendance/expense + PDF/CSV/XLSX export), shared reports, time off, holidays, expenses, approvals, custom fields, scheduling, invoices, and webhooks. 48 read tools are always available; 64 write tools are opt-in via CLOCKIFY_ACCESS_MODE (read | time-tracking | full). Auth is a single Clockify API key (X-Api-Key). Optional OpenTelemetry OTLP export for traces/metrics/logs.

Invgate Service Desk

@tracegazer

An open-source Model Context Protocol (MCP) server for the InvGate Service Desk / Service Management API. Exposes 96 tools across 11 domains — incidents (create, update, comment, reassign, approvals), users & groups, knowledge base, custom fields, assets/CIs, workflows, triggers, breaking news and time tracking. Read-only by default. Write access is opt-in via granular profiles: `support` (incidents + time tracking, KB stays read-only) or `full` (adds Knowledge Base writes). Backward compatible, fail-fast on misconfiguration, with optional OpenTelemetry instrumentation. Install: `uvx invgate-service-desk-mcp`. Published on PyPI and listed in the official MCP registry.
