Oraclaw MCP Server

OraClaw

MCP Optimization Tools for AI Agents -- 17 tools (11 free, no key), sub-25ms. Zero LLM cost.

Your AI agent can't do math. OraClaw gives it deterministic optimization, simulation, forecasting, and risk analysis through the Model Context Protocol. Every tool returns structured JSON, runs in under 25ms, and costs nothing to compute.

What this solves

LLMs generate plausible text, not mathematically optimal answers. OraClaw gives an AI agent a set of deterministic numerical tools it can call instead of guessing — each returns structured JSON from a real algorithm, with no token spend on reasoning. Concretely:

• Your agent needs to pick the next variant to try (A/B test arm, ad/email copy, recommendation) and balance exploration against exploitation — without hand-rolling a bandit or letting the model eyeball it. Call optimize_bandit (or optimize_contextual when the best choice depends on per-call features).
• Your agent needs a provably optimal allocation or schedule under hard constraints (budget split, integer counts, capacity caps) — without the model hallucinating constraints. Call solve_constraints (LP/MIP/QP via HiGHS) or solve_schedule for task-to-slot fitting.
• Your agent needs to quantify uncertainty around an outcome — project a value under an uncertain input, or measure VaR/CVaR on a weighted multi-asset book with auditable assumptions — without a Monte Carlo loop in the prompt. Call simulate_montecarlo, simulate_scenario, or analyze_risk.
• Your agent needs a point forecast or an outlier flag on a time series (demand, KPIs, sensor/metric streams) — without inventing trend math. Call predict_forecast (ARIMA / Holt-Winters) or detect_anomaly (Z-score / IQR).
• Your agent needs to fuse or score probability signals — combine model outputs, measure how much independent sources agree, or check whether past predictions were well-calibrated. Call predict_ensemble, score_convergence, or score_calibration.
• Your agent needs to reason over a graph — rank influential nodes, cluster a dependency/knowledge graph, find a critical path, or route between two nodes. Call analyze_graph or plan_pathfind.

Where the algorithms have been used

OraClaw's algorithms have informed implementations in several open-source projects -- through contributed routing specs, algorithm guidance, and shared math -- spanning AI agent orchestration, time-series tracking, vector search, and optimization.

Selected contributions (see CHANGELOG.md for the full list):

• chernistry/bernstein -- agent orchestration framework. LinUCB contextual router (α=0.3) with shadow-evaluation path and interpretable decision reasons, shipped in codex/issue-367-linucb-router after a contributed spec correction.
• stxkxs/nanohype -- contextual bandit routing, pluggable strategy registry (hash / sliding-TTL / semantic), cost anomaly detection. "Your input shaped a lot of what actually shipped."
• rfivesix/hypertrack -- Bayesian/Kalman-style adaptive estimator with phase-aware ramp. Shipped in 0.8.0-beta.
• AlanHuang99/pyrollmatch -- entropy balancing (Hainmueller 2012) with moment constraints + max_weight cap. Shipped in v0.1.3.
• stffns/vstash -- IDF-sigmoid relevance weighting. Shipped in v0.17.0.

Marketplace distribution:

• ✓ punkpeye/awesome-mcp-servers -- merged
• ✓ TensorBlock/awesome-mcp-servers -- merged
• ✓ MCP Registry, Glama (score A/A/B), PulseMCP, toolsdk-ai -- listed

Quick Start

1. MCP Server (recommended for AI agents)

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "oraclaw": {
      "command": "npx",
      "args": ["-y", "@oraclaw/mcp-server"]
    }
  }
}

Then ask your agent:

"I have 3 email subject line variants. Which should I send next?"

The agent calls optimize_bandit and gets a statistically optimal selection in 0.01ms.

2. REST API (no install)

curl -X POST https://oraclaw-api.onrender.com/api/v1/optimize/bandit \
  -H 'Content-Type: application/json' \
  -d '{
    "arms": [
      {"id": "A", "name": "Option A", "pulls": 10, "totalReward": 7},
      {"id": "B", "name": "Option B", "pulls": 10, "totalReward": 5},
      {"id": "C", "name": "Option C", "pulls": 2, "totalReward": 1.8}
    ],
    "algorithm": "ucb1"
  }'

Response (<1ms):

{
  "selected": { "id": "C", "name": "Option C" },
  "score": 1.876,
  "algorithm": "ucb1",
  "exploitation": 0.9,
  "exploration": 0.976,
  "regret": 0.1
}

Free tier: 25 calls/day, no API key needed.

3. npm SDK

npm install @oraclaw/bandit

import { OraBandit } from '@oraclaw/bandit';

const client = new OraBandit({ baseUrl: 'https://oraclaw-api.onrender.com' });
const result = await client.optimize({
  arms: [
    { id: 'A', name: 'Short Subject', pulls: 500, totalReward: 175 },
    { id: 'B', name: 'Long Subject', pulls: 300, totalReward: 126 },
  ],
  algorithm: 'ucb1',
});

14 SDK packages: @oraclaw/bandit, @oraclaw/solver, @oraclaw/simulate, @oraclaw/risk, @oraclaw/forecast, @oraclaw/anomaly, @oraclaw/graph, @oraclaw/bayesian, @oraclaw/ensemble, @oraclaw/calibrate, @oraclaw/evolve, @oraclaw/pathfind, @oraclaw/cmaes, @oraclaw/decide

Why?

LLMs generate plausible text, not optimal solutions. Ask GPT to pick the best A/B test variant and it applies a heuristic that ignores the exploration-exploitation tradeoff. Ask it to solve a linear program and it hallucinates constraints. OraClaw gives your agent access to real algorithms -- bandits, solvers, forecasters, risk models -- that return mathematically correct answers in sub-millisecond time, without burning tokens on reasoning.

Premium tools (detect_anomaly, predict_forecast, analyze_risk, solve_constraints, analyze_graph, optimize_cmaes) need an API key or an x402 payment — see Pricing below.

---

Pricing

x402 (for autonomous agents): pay $0.001/call in USDC on Base — no signup, no API key. Send a signed PAYMENT-SIGNATURE header on any premium endpoint; the API verifies, meters, and settles per call. Get a key instead with a one-line POST /api/v1/auth/signup ({"email":"you@…"}) — instant, no card.
