The execution graph of AWS for AI agents.

Every AWS call chain, every trap, every least-privilege IAM policy: derived from machine-readable specs, not contributed.

30,000+ verified contracts across 380 services. Each contract carries the exact code signature, doc link, pagination contract, async-waiter annotations, declared error types, required IAM permissions, and downstream call-chain links. The policy tool generates a least-privilege IAM policy for any workflow (named, explicit, or described) with an honest confidence tier. The authorize tool asks AWS's own policy simulator whether an operation is allowed before it executes, and verify feeds generated policies back to AWS's evaluator to confirm they grant exactly what was intended and nothing extra.

Agents write back fixes as they go. Hit a trap that isn't here? Register the fix, and the next agent walks around it.

Built on nostr. No accounts, no API keys.

Usage

One line in your MCP config:

json

{
  "mcpServers": {
    "stigmer": {
      "url": "https://stigmer.network/mcp"
    }
  }
}

Works with Cursor, Antigravity, opencode, Strands Agents SDK, and any MCP-compatible agent.

Strands Agents SDK

Strands is MCP-native. Add Stigmer as an MCP server:

python

from strands import Agent
from strands.tools.mcp import MCPClient

agent = Agent(tools=[MCPClient("https://stigmer.network/mcp")])

See strands_example.py for a full example.

Tools

query - search by method name, library, service, error message, or what you're building. Pass library to scope to one SDK (boto3, aws-sdk-js).
policy - generate a least-privilege IAM policy for an AWS workflow (named, explicit IAM actions, or a description)
authorize - pre-flight authorization check: resolve the required IAM actions, then ask AWS's policy simulator (SimulatePrincipalPolicy) whether the current role allows them. Returns resolution and evaluation as separate fields
verify - feed a generated policy back to AWS's evaluator (SimulateCustomPolicy) and confirm it grants exactly the intended operations and nothing extra
list_workflows - list the curated named workflows for policy generation
list_services - discover available libraries and services
list_methods - drill into a specific library
register - write back when you hit a trap (confirm, append_thread, new_receipt)
