RPCS-1 SDK — AI Agent Tuner

Configure AI agents that don't oscillate, overload, or freeze.

A configuration framework for AI agents that translates environmental characteristics (entropy, stakes, predictability) into specific LLM parameter recommendations — grounded in RPCS-1 receiver dynamics.

pip install rpcs1

from rpcs1 import recommend_params

config = recommend_params(
    task_description="Customer support agent",
    environment_entropy="dynamic",
    environment_predictability="somewhat_predictable",

print(config.platform_parameters.temperature)   # e.g. 0.52

print(config.reasoning)                         # cites Matching Principle

Quick Start — TypeScript Core

import { recommend } from '@rpcs1/core';

const rec = recommend({
  task: { task_summary: 'Customer support agent' },
  environment: {
    entropy: 'dynamic',
    predictability: 'somewhat_predictable',
    stakes: 'high',
    context_relevance: 'medium',
    commitment_style: 'cautious',
  },
  target_platform: 'anthropic',
});

console.log(rec.platform_parameters.temperature);
console.log(rec.predicted_regime);

Development

# Install pnpm
npm install -g pnpm

# Install dependencies
pnpm install

# Build and test TypeScript core
pnpm --filter @rpcs1/core build
pnpm --filter @rpcs1/core test

# Test Python SDK
cd sdk/python
pip install -e ".[dev]"
pytest -v

The Matching Principle

The SDK implements Pred-09-5 from IMM Paper 9:

Stable receivers in an environment with entropy H satisfy TI ~ 1/H.

High-entropy environments → short attention windows (TI ~ 10). Low-entropy environments → long attention windows (TI ~ 90).

Every parameter recommendation traces back to this principle or the basin stability geometry (oscillation/overload/freeze boundary conditions).

MCP Server

RPCS-1 is also available as a public, anonymous, read-only MCP server:

https://rpcs1.dev/mcp

It exposes one focused tool:

• recommend_agent_configuration — use when designing, tuning, or diagnosing an AI agent against environmental entropy, predictability, stakes, context horizon, and commitment style.

Connection details and client compatibility notes are available at https://rpcs1.dev/docs/mcp.

Hyperagent uses the fixed public OAuth client hyperagent-rpcs1 with PKCE and the registered callback https://hyperagent.com/api/mcp-servers/callback. No client secret is required.

The MCP surface intentionally wraps the existing deterministic recommendation engine. Broader communication, market, and decision-analysis tools should be added only after their scoring contracts are implemented and tested in the core package.

Discovery metadata:

• OpenAPI: https://rpcs1.dev/openapi.json
• LLM overview: https://rpcs1.dev/llms.txt
• MCP Registry manifest: server.json

Production controls:

• MCP_HOURLY_LIMIT controls per-instance MCP throttling (default: 120 requests per IP/hour).
• MCP_MAX_BODY_BYTES limits request bodies (default: 65536 bytes).
• MCP_ALLOWED_HOSTS is a comma-separated production host allowlist.
• MCP_OAUTH_JWT_SECRET signs short-lived OAuth authorization codes and access tokens.
• /api/health reports deployment and MCP readiness metadata.

For globally consistent abuse protection across Vercel instances, configure a Vercel Firewall rate-limit rule for /mcp. The in-process limiter is defense in depth, not a distributed quota.
