Topology Index is an MCP server with 6 tools an agent can call, among them fetch, get_pattern, list_patterns. It answers at https://topologyindex.com/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 4 of 4 times since 23 September 2026; the last check, on 7 November 2026, succeeded.
Read-only reference for choosing multi-agent LLM topologies: patterns, aliases, sources, starters.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
fetch | Returns the Markdown document of any public page, exactly as HTTP serves it, from a root-relative path (/patterns/supervisor.md) or a https://topologyindex.com URL. Private tenant routes are not reachable here. A pattern, starter or formati Inputs: path_or_url |
get_pattern | One pattern page (/patterns/{pattern}.md): definition, aliases, when it is hypothesised to fit, failure modes, sources and whether this deployment can execute it. Accepts a pattern identifier or a known alias. Adds a second item with a one- Inputs: pattern |
list_patterns | The decision guide: where to start by the shape of the task, the pattern to consider next and when to avoid each, plus the pattern families (the `choosing` rows of /patterns/index.md, without the rest of that page). With a family, /patterns Inputs: family, domain |
list_starters | The starter formation index (/starters/index.md): unvalidated, unsigned FORMATION.md documents to copy and register privately. With a task class, only the starters that declare it (/starters/index.md?task_class={task_class}). The response i Inputs: task_class |
report_outcome | Limited rollout: only for a use ticket from a pattern, starter or formation read. If you have no ticket, do not call it. With one, report once after applying it when you know the outcome: `worked`, `partly` or `did_not_work`, with an option Inputs: ticket, outcome, note |
search | Keyword search, with common synonyms, over pattern names, aliases and families, the decision guide, the domains, sources and benchmarks of published findings, research, starters and guides. At most 10 results, each a path for `fetch`; canon Inputs: query |

It answered our last check on 7 November 2026 in 186 ms. Over 4 checks since 23 September 2026 it answered 4. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by topologyindex.com and served from topologyindex.com, the vendor's own domain: https://topologyindex.com/mcp.
6, as returned by the server's own tools/list on 13 November 2026: fetch, get_pattern, list_patterns, list_starters, report_outcome, search.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://topologyindex.com/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: com.topologyindex. Endpoint host: topologyindex.com. ARD identifier: urn:air:com.topologyindex:mcp:topology-index.
First indexed 23 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.
