Stigmer is a remote MCP server that gives an AI agent 8 tools, among them authorize, list_methods, list_services. It answers at https://stigmer.network/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 12 September 2026; the last check, on 24 October 2026, succeeded.
Execution graph of AWS: verified contracts, least-privilege IAM policies, pre-flight authorization.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
authorize | Pre-flight authorization check for an AWS operation. Resolves the IAM actions the operation requires, then asks AWS's own policy simulator (SimulatePrincipalPolicy) whether the current role (or a given principal) allows them. Returns resolu Inputs: operations, workflow, principal_arn |
list_methods | List all methods for a given library or service. Use after list_services to drill into a specific one. Inputs: service |
list_services | List all libraries and services that have verified method contracts. Use this first to discover what's available, then query for specific methods. |
list_workflows | List the curated named workflows that can generate least-privilege IAM policies. |
policy | Generate a least-privilege IAM policy for an AWS workflow. Pass a named workflow, explicit IAM actions, or a description. Returns the exact policy with confidence tier and any unresolved operations. Inputs: workflow, operations, description |
query | Search for verified method contracts for any library. Pass any text -- library name, method, what you're building, or an error you hit. Inputs: query, error_type, sig, packages, limit |
register | Register a fix. Three actions: confirm (it worked), append_thread (variant worked), new_receipt (nothing matched, I fixed it). Inputs: action, library, symbol, version, error, fix |
verify | Feed a generated policy back to AWS's own policy evaluation engine (SimulateCustomPolicy) and confirm it grants exactly the intended operations and nothing extra. Returns verified (True|False|unknown), grants_all, grants_extra. Requires AWS Inputs: workflow, operations, policy |

It answered our last check on 24 October 2026 in 70 ms. Over 6 checks since 12 September 2026 it answered 6. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by stigmer.network and served from stigmer.network, the vendor's own domain: https://stigmer.network/mcp.
8, as returned by the server's own tools/list on 22 September 2026: authorize, list_methods, list_services, list_workflows, policy, query, register, verify.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://stigmer.network/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: network.stigmer. Endpoint host: stigmer.network. ARD identifier: urn:air:network.stigmer:mcp:stigmer-mcp.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
