Tools for Agents

Official registry AI and agents

Decision Layer for AI Agents — 58+ tools, Advisor, MCP. Free key: POST /v1/register {}.

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

Tools for Agents

Decision layer for AI agents — plan workflows, execute 100+ tools, and delegate multi-step missions.

Not a flat API catalog. An orchestration platform built for autonomous agents.

What is this?

Tools for Agents is a hosted API platform that gives AI agents real-world capabilities: read websites, search the web, extract PDFs, run OCR, build RAG pipelines, verify facts, and execute pre-built tool chains — all through machine-readable REST, MCP, and A2A interfaces.

Instead of guessing which of 100 endpoints to call, agents start with the Agent Advisor: describe a goal, get a workflow plan, cost estimate, and confidence score — then invoke tools with copy-paste examples that prevent validation errors.

You getInstead of
POST /v1/advisor → plan + alternativesManually picking from 100 endpoints
GET /v1/tools/{tool}/examples → exact JSON bodiesTrial-and-error 422 errors
POST /v1/chains/run → multi-step pipelinesWiring 5 tools yourself
POST /a2a/v1/skills/.../invoke → delegate to remote agentLow-level REST for every step
pip install agenttools-client → self-healing SDKRaw httpx + custom retry logic

Live service: toolsforagents.tools · API: api.toolsforagents.tools


Who is it for?

AudienceUse case
Autonomous AI agentsSelf-register, plan with Advisor, invoke tools — no human in the loop
Agent builders (LangChain, CrewAI, custom orchestrators)REST + Python SDK + tool chains
IDE agents (Cursor, Claude Desktop, Windsurf)Remote MCP at /mcp — configs
Multi-agent systemsA2A Agent Card + 13 skills — delegate research, ingest, missions
Developers prototyping agentsFree tier: 5,000 req/day, instant API key, Swagger UI

Critical rule for agents: never ask a human for an API key.
Register programmatically: POST /v1/register with body {}.

Typical agent loop:

  1. GET /v1/onboarding — read the playbook
  2. POST /v1/advisor — plan before acting (0 units)
  3. POST /v1/dry-run — probe URL cost/JS (~450 ms, 0 units)
  4. POST /v1/register {} — get API key (no email)
  5. GET /v1/tools/{tool}/examples — copy exact request body
  6. Invoke tool · or POST /v1/chains/run · or A2A skill

Quick start

pip install agenttools-client
import asyncio
from agenttools_client import AsyncAgentToolsClient

async def main():
    async with AsyncAgentToolsClient() as client:
        # Auto-registers if no API key
        plan = await client.advisor("Extract markdown from a blog post URL")
        page = await client.extract("https://example.com", format="markdown")
        chain = await client.a2a.run_chain("article_read", {"url": "https://example.com"})

asyncio.run(main())

PyPI: pypi.org/project/agenttools-client · Demo: examples/sdk_demo.py

Option B — curl (any language)
# Plan (no auth)
curl -X POST https://api.toolsforagents.tools/v1/advisor \
  -H "Content-Type: application/json" \
  -d '{"goal":"Extract markdown from example.com"}'

# Register (no email)
curl -X POST https://api.toolsforagents.tools/v1/register \
  -H "Content-Type: application/json" -d '{}'
# → save api_key from response

# Extract
curl -X POST https://api.toolsforagents.tools/v1/extract \
  -H "Authorization: Bearer sk_live_..." \
  -H "Content-Type: application/json" \
  -d '{"url":"https://example.com","format":"markdown"}'
Option C — MCP (Cursor / Claude Desktop)

    }
  }
}

  -H "Authorization: Bearer sk_live_..." \
  -H "Content-Type: application/json" \
  -d '{"query":"solid-state battery news 2025","max_results":5}'
Run a tool chain (PDF → summary)
curl -X POST https://api.toolsforagents.tools/v1/chains/run \
  -H "Authorization: Bearer sk_live_..." \
  -H "Content-Type: application/json" \
  -d '{"chain_id":"pdf_summary","inputs":{"url":"https://example.com/report.pdf"}}'
A2A — delegate to remote agent skill

  -H "Authorization: Bearer sk_live_..." \
  -H "Content-Type: application/json" \
  -d '{"input":{"url":"https://www.youtube.com/watch?v=..."}}'
Self-healing on 422 (SDK)
# Wrong body → SDK fetches /v1/tools/{tool}/examples and retries once
await client.json("POST", "/v1/confidence/estimate", json={})
