Nothing serious here today

Today is the operative word: we check Symbola every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

pack

get_pack

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.

read_pack_file

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.

build

get_build_steps

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.

decisions

read_decisions

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.

packs

search_packs

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.

Symbola — questions

Answers built from our own checks of this server.

What can Symbola do?

It exposes 5 tools, read directly from the server on our last check. Among them: get_build_steps, get_pack, read_decisions, read_pack_file, search_packs. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Symbola working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 181 ms. The bar chart above shows every period we have measured.

How do I connect Symbola?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Symbola need an API key?

No. Symbola completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Symbola?

It answers our handshake in 181 ms on average, which is faster than 77% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
