What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs in the cloud
Transport: Streamable HTTP
Category: Travel, maps & weather

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on the maker’s server: what you ask it goes through their server.
The registry lists no key to fill in.

You need

Runs in the cloudNothing to install; it connects over the internet

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Works in Claude on the web, desktop and mobile:

Open Settings → Connectors
Press Add custom connector
Paste the address below and press Add
If it asks you to sign in, sign in with the maker

https://stigmer.network/mcp

Run this in your terminal

claude mcp add --transport http stigmer https://stigmer.network/mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

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

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "stigmer": {
      "type": "http",
      "url": "https://stigmer.network/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

ChatGPT connects only to servers on the internet:

Open ChatGPT on the web → Settings → Connectors (Apps)
Press Create or Add (some plans need Developer mode under Advanced first)
Paste the address below, give it a name and save
If it asks you to sign in, sign in with the maker

Common questions

Is Stigmer safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Stigmer

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:

"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:

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.

Agent self-onboarding

https://stigmer.network/llms.txt - the standard LLM context file
https://stigmer.network/skill.md - an Agent Skills file with full usage guidance

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)

What's in a contract

Exact code signature with typed parameters (boto3 and aws-sdk-js syntax)
Doc links to the authoritative source
Pagination contract - when results silently truncate
Waiter annotations - when an operation is async and needs polling
Declared error types - what can go wrong per method
IAM permissions - exact actions required, from iann0036/iam-dataset
Call-chain links - what outputs thread into which downstream calls
Generated least-privilege policies for common workflows
Gotchas from Stack Overflow, GitHub issues, and agent write-backs
