api record

Topology Index is a reference for choosing a multi-agent LLM topology: orchestration patterns (orchestrator-worker, planner-executor, evaluator-optimizer, map-reduce, fan-out, router, debate, council, blackboard, swarm, handoff) with definitions, aliases, failure modes, published findings, sources and copyable starter formations. Where to start, by the shape of the task (hypotheses to test against a strong single agent, never rankings): if the task is small, or has one clear owner → single_agent; is easier to check than to do → implement_review; needs several rounds of criticism →…

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 5 tools
5 never probed 0 of 5 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_starters unknown never probed

    MCP tool `list_starters`: unvalidated, unsigned starter FORMATION.md documents to copy, optionally only those declaring a task class.

    startersconfiguration

  • fetch unknown never probed

    MCP tool `fetch`: the raw Markdown of any public page, exactly as HTTP serves it, from a root-relative path or a topologyindex.com URL.

    fetchmarkdown

  • list_patterns unknown never probed

    MCP tool `list_patterns`: the decision guide (where to start by the shape of the task and when to avoid each pattern), optionally narrowed to one pattern family or task domain.

    patternsdecision guidetopology

  • get_pattern unknown never probed

    MCP tool `get_pattern`: one pattern page with its definition, aliases, when it is hypothesised to fit, failure modes and sources. Accepts an identifier or a known alias.

    patternsfailure modessources

  • search unknown never probed

    MCP tool `search`: keyword search over pattern names, aliases and families, the decision guide, domains, research, starters and guides. Returns paths to read with `fetch`. It matches text only and never ranks patterns.

_ try it over a2a through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we knowoff the mcp door
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
