topolift-mcp 0.1.1

MCP server exposing TopoLift's atom-grounded negotiation reasoning to any MCP-compatible agent (Claude Code, Cursor, OpenAI Agents SDK, etc).

topolift-mcp

MCP server exposing TopoLift's atom-grounded negotiation reasoning to any MCP-capable agent — Claude Code, Cursor, OpenAI Agents SDK, etc.

Listed on the official MCP Registry as io.github.TopoLift/topolift-mcp.

mcp-name: io.github.TopoLift/topolift-mcp

What you get

Two tools:

• topolift_dialect — fetches TopoLift's published vocabulary (regimes, canonical strategies, signal keys, citation grammar). Call this once at session start; no auth required.
• topolift_negotiate — sends a negotiation context to TopoLift's reasoning engine and returns a bilingual response:
  • A typed topology slot (regime, load_bearing_strategies[], bridge_pivots[], topology_signals{}) drawn from a closed vocabulary
  • Prose fields with inline [Cluster_X#strategy1,strategy2] citation tokens anchoring every claim to the cluster + load-bearing atoms that drove it

Atoms stay on the TopoLift server. What travels is the grammar of the dialect — the vocabulary your agent uses to read structural reasoning.

Install

pip install topolift-mcp

Set your API key (get one at https://topolift.ai):

export TOPOLIFT_API_KEY=tl-...

Claude Code

claude mcp add topolift-negotiation -- topolift-mcp

…or, with the API key inline:

claude mcp add topolift-negotiation -e TOPOLIFT_API_KEY=tl-... -- topolift-mcp

Cursor / Continue / other MCP clients

Add to your MCP config (~/.cursor/mcp.json or equivalent):

{
  "mcpServers": {
    "topolift-negotiation": {
      "command": "topolift-mcp",
      "env": {
        "TOPOLIFT_API_KEY": "tl-..."
      }
    }
  }
}

Running directly (no install)

TOPOLIFT_API_KEY=tl-... python -m topolift_mcp.server

Configuration

Environment variables:

Var	Default	Purpose
TOPOLIFT_API_KEY	(required for negotiate)	Bearer key; get one at https://topolift.ai
TOPOLIFT_API_URL	https://api.topolift.ai	API base URL
TOPOLIFT_TIMEOUT	600	Negotiate-call timeout in seconds
TOPOLIFT_LOG_LEVEL	INFO	Python logging level

The dialect tool works without TOPOLIFT_API_KEY — only topolift_negotiate requires it.

Pricing

• Bearer key (this MCP server's path): one-time / monthly plans starting at $50. See https://topolift.ai.
• x402 micropayment: agents can pay $0.10 USDC per call directly against https://api.topolift.ai/v1/negotiate with no API key — see the API's 402 challenge for details.

How it works

1. Your agent calls topolift_dialect once and learns the vocabulary.
2. Your agent calls topolift_negotiate with a scenario.
3. TopoLift retrieves the most relevant atom clusters from its server-side topology, runs a Mistral-Small-4-119B reasoning pass with a closed-vocabulary prompt, and returns the bilingual response.
4. Your agent parses topology for machine-readable structure and reads the prose fields with citation-traceable evidence.

The atoms — the structural primitives — never leave TopoLift's servers. The dialect — the names and the grammar — is published openly so any agent can read structural reasoning fluently.
