mirofish-mcp-server

MCP (Model Context Protocol) server for MiroFish — the AI-powered multi-agent prediction engine. Connect Claude Code (or any MCP-compatible AI client) directly to your local MiroFish instance.


What this does

MiroFish lets you upload documents, build a knowledge graph, spin up thousands of autonomous AI agents, and simulate future scenarios. This MCP server exposes all of that as tools Claude can call directly from a conversation.

Prerequisites

  1. Node.js 18+

  2. MiroFish running locally — clone and start it first:

git clone https://github.com/666ghj/MiroFish.git
cd MiroFish
cp .env.example .env
npm run setup:all
npm run dev            # starts backend at http://localhost:5001

Using Claude as MiroFish's LLM — MiroFish accepts any OpenAI-compatible API. To use Claude, set these in your MiroFish .env:

LLM_API_KEY=sk-ant-api03-...          # your Anthropic API key
LLM_BASE_URL=https://api.anthropic.com/v1
LLM_MODEL_NAME=claude-sonnet-4-6
ZEP_API_KEY=...                        # still required for the knowledge graph

MiroFish's LLM client passes base_url directly to the OpenAI SDK, so Claude handles all internal AI work — ontology extraction, agent profiling, simulation decisions, report generation — with no code changes.


Installation

git clone https://github.com/thisisaman408/mirofish-mcp-server.git
cd mirofish-mcp-server
npm install
npm run build

Connect to Claude Code

Create a .mcp.json file in the directory where you run Claude Code (or your project root):

{
  "mcpServers": {
    "mirofish": {
      "command": "node",
      "args": ["/absolute/path/to/mirofish-mcp-server/dist/index.js"],
      "env": {
        "MIROFISH_BASE_URL": "http://localhost:5001"
      }
    }
  }
}

Replace /absolute/path/to/ with the actual path where you cloned this repo. Then restart Claude Code — the MiroFish tools will appear automatically.

Custom backend URL

If MiroFish runs on a different host or port, change MIROFISH_BASE_URL:

"env": {
  "MIROFISH_BASE_URL": "http://192.168.1.10:5001"
}

Example conversation with Claude

Once connected, you can talk to Claude naturally:

"List my MiroFish projects"

"Create a simulation about public opinion on climate policy using project proj_abc123"

"Interview agent Li Wei — ask her what she thinks about the new carbon tax"

"Generate a prediction report for simulation sim_xyz789 and show me the executive summary"

"Search the knowledge graph for anything about social media sentiment"


Workflow

The typical end-to-end flow in MiroFish:

1. Generate ontology   →  mirofish_generate_ontology  (upload docs)
2. Build graph         →  mirofish_build_graph         (async, poll with get_task)
3. Create simulation   →  mirofish_create_simulation
4. Prepare simulation  →  mirofish_prepare_simulation  (async, generates agent profiles)
5. Start simulation    →  mirofish_start_simulation
6. Monitor / results   →  get_posts, get_actions, get_timeline
7. Generate report     →  mirofish_generate_report     (async)
8. Interview agents    →  mirofish_interview_agent
9. Chat about results  →  mirofish_chat_with_report_agent

Development

# Edit src/index.ts, then rebuild
npm run build

# Run directly (requires MiroFish backend)
node dist/index.js

The server uses stdio transport — Claude Code launches it as a subprocess and communicates over stdin/stdout.
