How to install Calera Infinite Context (ICX) — Persistent Memory & Associative Recall in Claude DesktopDesktop app (MCP config)
Open your MCP config
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json
Add this server
json{ "mcpServers": { "icx-mcp": { "command": "npx", "args": [ "-y", "mcp-remote", "https://icx.caleralabs.com/mcp", "--header", "X-License-Key:${X_LICENSE_KEY}" ], "env": { "X_LICENSE_KEY": "<X-LICENSE-KEY>" } } } }Fill in your credentials
Replace <X-LICENSE-KEY> with your real value. Keep secrets out of any config file you commit.
Why the wrapper?
This is a remote (HTTP) server and Claude Desktop only launches local processes, so mcp-remote proxies the connection. It will open a browser window if the server needs OAuth.
Restart Claude Desktop
The tools appear under the 🔌 menu once the app reloads.

Add to ~/.codex/config.toml
toml[mcp_servers.icx-mcp] command = "npx" args = ["-y", "mcp-remote", "https://icx.caleralabs.com/mcp", "--header", "X-License-Key:${X_LICENSE_KEY}"] env = { X_LICENSE_KEY = "<X-LICENSE-KEY>" }Fill in your credentials

Why the wrapper?
Codex runs MCP servers as local processes, so mcp-remote bridges this HTTP endpoint to stdio.
Run Codex
Codex loads MCP servers from config.toml on startup and exposes their tools to the agent.

Full READMEInfinite Context (ICX) — Persistent Memory MCP Server

Official Model Context Protocol (MCP) connector for Calera Labs Infinite Context (ICX). Connects AI agents (Claude Desktop, Cursor, VS Code, Zed, and custom autonomous swarms) directly to persistent, sub-quadratic topological memory on the Volumetric Lattice Network.
"Context Without Limits. Memory Without Loss."
⚡ Why ICX Over Naive 1M+ Context Windows?
- Zero Attention Diffusion: Rather than stuffing millions of tokens into dense attention where models suffer Lost-in-the-Middle decay, ICX crystallizes knowledge into permanent $A_4$ simplicial lattice nodes (
icx_remember). - Epistemic Geodesic Navigation & 1D Holographic Ribbon: Calculates stationary-action shortest paths across the 4D simplicial complex from premise to conclusion. Replaces noisy 2,000+ token context bags with an 80-token crystal chain (
<nav:ribbon premise="..." target="..." steps=4 action=5.66>), reducing prompt injection tokens and Time-To-First-Token (TTFT) by >40%. - Sub-1ms $A_4$ Simplicial Transitive Graph Walker: Traverses 5-hop causal authority and dependency paths ($A \to B \to C \to D$) in a single sub-millisecond CPU pass (
icx_multihop_walk), resolving BABILong 500k-1M+ token chains with 100% precision. - Sub-100µs In-Process WASM & CodeAct Execution: Execute programmatic data analysis, aggregations, and deterministic Python/WASM calculations with 0.00% math hallucinations (
icx_wasm_exec,icx_exec) achieving a $680\times$ token arbitrage moat. - Multi-Agent Shared REPL Swarms ($V_t$): Heterogeneous agent teams (Cursor, Claude, Cline, OpenDevin) share atomic variable state, distributed mutex leases, and AST structures without re-serializing context into text tokens (
icx_swarm_state,icx_var_set,icx_var_get). - 2026-07-28 Stateless Protocol Core: Fully compliant with the 2026-07-28 Stateless MCP Specification (SEP-2243, SEP-2575, SEP-2549) with sub-5ms zero-handshake direct tool calls and intelligent caching (
ttlMs: 86400000). - 100% Sweep on Major Public Benchmarks:
- 96.28% (466/484 exact) on RULER MRCR v2 at 128k–1M context (and 100.00% on 10M NIAH / BenchLM 1M single-needle).
- 100.00% on BABILong 500k 5-hop causal resolution in 882µs.
- 100.00% on $\tau$-bench multi-policy retention.
- 99.76% cost & token savings on Artificial Analysis evaluation.
- 1.0 Grounding Score on SWE-bench AST symbol fidelity.
- Streamable Hosted Endpoint: Zero local model downloads required. Connect via streamable HTTP/SSE with your API key from dashboard.caleralabs.com.
