api record

Symbola (https://symbola.sh) is a registry of packs. A pack is a piece of software shipped as its decisions: a product description (PRODUCT.md), a brief, assumptions, the decisions a builder could get wrong, and components with examples and checks. A coding agent builds the software from the pack, in any language.

Use search_packs to find packs, get_pack for an overview, read_decisions and read_pack_file to answer questions about what a pack decides, and get_build_steps when the user wants it built. Building needs a shell (Claude Code or another coding agent); in a chat without one, explain…

_ is it live, free and safe measured by this hub
Is symbola live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is symbola free to use?
Yes — the hub reached it with no key and no payment.
What tools does symbola have?
5 tools: read_decisions, read_pack_file, get_build_steps, get_pack, search_packs.
Is symbola safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

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.

  • search_packs open 1h ago

    Search the Symbola registry for packs: software a coding agent can build from its decisions. Matches words against each pack's name, summary, id and category. With no query, lists every pack.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "limit": {
      "type": "integer",
      "maximum": 50,
      "minimum": 1,
      "description": "Most packs to return (default 10)."
    },
    "query": {
      "type": "string",
      "description": "Words to look for, e.g. \"paper library\" or \"encrypted meetings\"."
    },
    "category": {
      "type": "string",
      "description": "Only packs in this category: research, finance, text, data, places, time, dev, productivity or other."
    }
  }
}
    arguments 19 lines
  • read_decisions unknown never probed

    The decisions a pack makes: each one a rule a builder could get wrong, with its status (decided, default or open). Narrow them to one component or to decisions mentioning some words.

    mcp-tool

    {
  "type": "object",
  "required": [
    "pack"
  ],
  "properties": {
    "pack": {
      "type": "string",
      "description": "The pack id, owner/name, e.g. kausalflow/lightkone. A symbola.sh pack link works too."
    },
    "query": {
      "type": "string",
      "description": "Only decisions whose id or text contains all of these words."
    },

      "enum": [
        "decided",
        "default",
        "open"
      ],
      "type": "string",
      "description": "Only decisions with this status."
    },
    "component": {
      "type": "string",
      "description": "Only decisions checked in this component, e.g. search-query."
    }
  }
}
    arguments 29 lines
  • read_pack_file unknown never probed

    Read one file of a pack, e.g. PRODUCT.md (the whole product), AGENTS.md (how to build it), BRIEF.md, obligations.toml, an assumption, or a component's symbolon.toml or examples.jsonl. "pack.md" is the whole pack as one Markdown page.

    mcp-tool

    {
  "type": "object",
  "required": [
    "pack",
    "path"
  ],
  "properties": {
    "pack": {
      "type": "string",
      "description": "The pack id, owner/name, e.g. kausalflow/lightkone. A symbola.sh pack link works too."
    },
    "path": {
      "type": "string",
      "description": "The file's path inside the pack, e.g. PRODUCT.md."
    }
  }
}
    arguments 17 lines
  • get_build_steps unknown 1h ago

    How to build a pack: the steps a coding agent with a shell follows (install the symbola CLI, pull the pack, build each component and run its checks), and a one-line request the user can paste into Claude Code or another coding agent.

    mcp-tool

    {
  "type": "object",
  "required": [
    "pack"
  ],
  "properties": {
    "pack": {
      "type": "string",
      "description": "The pack id, owner/name, e.g. kausalflow/lightkone. A symbola.sh pack link works too."
    },
    "language": {
      "type": "string",
      "description": "The language or stack to build in, e.g. Python, Go, TypeScript."
    }
  }
}
    arguments 16 lines
  • get_pack unknown 1h ago

    Overview of one pack: what it builds, its version, how many decisions it holds, its components, its page and download link, and the files it holds.

    mcp-tool

    {
  "type": "object",
  "required": [
    "pack"
  ],
  "properties": {
    "pack": {
      "type": "string",
      "description": "The pack id, owner/name, e.g. kausalflow/lightkone. A symbola.sh pack link works too."
    }
  }
}

_ try it 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.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 19cbf91537132aee.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/19cbf91537132aee/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/19cbf91537132aee/badge.svg)](https://brick.blue/agent/19cbf91537132aee?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
90%

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.

_ record

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