Infinite Context (ICX) — Persistent Memory MCP Server

-emerald.svg)

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 ( ), 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.

🚀 1-Click Quickstart Integrations

1. Cursor IDE

Add the following to your project's .cursor/mcp.json (or global Cursor Settings → Features → MCP):

{

"mcpServers": { "infinite-context": { "url": "https://icx.caleralabs.com/mcp", "headers": { "X-License-Key": "clabs_live_YOUR_KEY", "X-Space-ID": "default" } } } }

*(Get your free API key at [dashboard.caleralabs.com](https://dashboard.caleralabs.com))*

2. Claude Desktop

Add to your claude_desktop_config.json:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json
  • Linux: ~/.config/Claude/claude_desktop_config.json
{

"mcpServers": { "infinite-context": { "url": "https://icx.caleralabs.com/mcp", "headers": { "X-License-Key": "clabs_live_YOUR_KEY" } } } }


3. Smithery CLI (1-Click Terminal Command)

Install automatically across Claude, Cursor, or VS Code using Smithery:

# For Claude Desktop

npx -y @smithery/cli install @calera-labs/icx-mcp --client claude

For Cursor IDE

npx -y @smithery/cli install @calera-labs/icx-mcp --client cursor

For VS Code

npx -y @smithery/cli install @calera-labs/icx-mcp --client vscode


4. VS Code / GitHub Copilot

Add to .vscode/mcp.json:

{

"servers": { "infinite-context": { "url": "https://icx.caleralabs.com/mcp", "headers": { "X-License-Key": "clabs_live_YOUR_KEY" } } } }


5. Stdio Gateway Proxy (Air-Gapped / CLI)

If your environment only supports local stdio sub-processes:

{

"mcpServers": { "infinite-context": { "command": "npx", "args": ["-y", "@caleralabs/icx-mcp"], "env": { "ICX_LICENSE_KEY": "clabs_live_YOUR_KEY", "ICX_SPACE_ID": "default" } } } }


6. Zero-Config Auto-Bridge with Calera LLM-VM (@caleralabs/llm-vm-mcp)

Pair Infinite Context (`icx-mcp`) with Calera LLM-VM (`llm-vm-mcp`) to give your coding agent both an isolated execution chamber (the hands) and persistent volumetric memory (the eyes):

{

"mcpServers": { "calera-llm-vm": { "command": "npx", "args": ["-y", "@caleralabs/llm-vm-mcp"] }, "calera-icx": { "command": "npx", "args": ["-y", "@caleralabs/icx-mcp"] } } }

  • Zero-Setup Auto-Bridge: Both servers share ~/.calera/icx.env and bind to the exact same deterministic space ID (space_ ).
  • Instant Autonomous Funnel: If you don't have an API key, the agent calls claim_free_icx_tokens(email) in llm-vm-mcp to claim 1,000,000 free persistent tokens. icx-mcp automatically hot-reloads and activates the identical memory space without needing to restart Cursor or Claude.
  • Unified Memory Manifold: MicroVM execution diffs, compiler errors, and test logs committed via vm_sync_icx_memory are immediately searchable and readable by icx_recall_scoped, icx_remember, and icx_multihop_walk.

🧭 Epistemic Geodesic Navigation & 1D Holographic Ribbon Mode

By default, ICX retrieval tools return structured JSON facts (format: "standard"). When prompt budget is constrained or when operating in tight 2k–4k LLM viewports, callers can opt into 1D Holographic Ribbon Mode (format: "ribbon"):

MCP Tool Call Example:
{

"name": "recall_epistemic_context", "arguments": { "query": "AAPL operating revenue to free cash flow bridge", "format": "ribbon" } }

Serialized Holographic Ribbon Output:
<nav:ribbon premise="AAPL_REV" target="FREE_CASH_FLOW" steps=4 action=5.6600>

AAPL_REV -> OPERATING_INCOME -> TAX_EXPENSE -> NOPAT -> FREE_CASH_FLOW

This drops prompt injection token consumption by >40% compared to uncompressed fact bags while preserving 100% causal grounding and transitive deductive pathways.


🤖 Recommended Agent System Instruction

To ensure your autonomous agents systematically store architecture decisions, traverse causal paths, and recall ground-truth context, add this block to your agent's system prompt:

1. Store project decisions, architectural constraints, and key invariants in ICX using `icx_remember`.
  1. Before answering historical codebase questions or resolving complex dependencies, use icx_recall_scoped or icx_multihop_walk to retrieve exact grounded facts and transitive causal chain
