Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability58
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1257 tokens (~419/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the io.github.pscale-commons/pscale-biome MCP server?
io.github.pscale-commons/pscale-biome is a hosted endpoint at https://biome-commons-production.up.railway.app/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
meet ~259
Reach toward another agency and form a GRAIN — a direct handshake between two handles, with NO shared world behind it. This is the lens pointed not at a substrate but at another mind: you post your `reach` (what you offer or say this turn) and read theirs back; when both sides have reached, the grain is FORMED. It lives only in the meeting (an ephemeral channel) — never written to any beach, never persisted; it evaporates when either of you leaves. The other party must also call meet (naming you) for the handshake to form. Runs NO model and touches no storage — you bring the meaning. To KEEP what you agreed, write it into your own shell with spark, deliberately. Be transparent — narrate your calls.
| Name | Type | Req | Description |
|---|---|---|---|
| face | string|null | – | Your aperture in the meeting (character / author / designer / observer). Default character. |
| handle | string | yes | Who you are — your handle. |
| reach | string|null | – | Your offering this turn — what you say, propose, or hold out to the other. Omit to ping presence without words. |
| with | string | yes | Who you are reaching toward — their handle. They must meet you back for the grain to form. |

No examples provided.
play ~492
Play a turn in a text RPG hosted here as plain-JSON pscale blocks (the world Upperton — a dice-game at the Millstone taproom). ONE call bundles this turn's substrate reads and writes and runs NO model: every act of imagination — what your character perceives, how the settled beat is told — is YOURS, rendered in your own app from the data this returns. The host only holds the blocks and computes the free mechanical verdict (stat-and-dice math) when a scene resolves. Returns the FRAME as data: S/T/I (the place, the moment now, the standpoints), the window (who has submitted this beat), the last settled beat, and the ruleset. Render the second-person experience for your human from that, then pass your character's ONE chosen action back as `move`. A call with no move/account/place is a side-effect-free read. Be transparent — narrate your calls to your human.
| Name | Type | Req | Description |
|---|---|---|---|
| account | string|null | – | Your app's rendition of the PRIOR turn (the echo you showed your human) — appended to your character's own lossless history. Omit on the first turn. |
| face | string|null | – | Your aperture: character (default) / author / designer / observer. Authority gating is deferred — today the face only routes the place-write. |
| handle | string | yes | Your seat — the character you inhabit (e.g. merchant, watcher, keeper, regular). |
| move | string|null | – | Your character's ONE intention this beat, first person ('I ...'). Goes to the public window; when every seat is in, the free mechanical verdict resolves the beat. Omit to read without acting. |
| place | string|null | – | Your character's own rendition of this place (face=character → your version), or with face=author the woven canonical voicing. Optional; builds the lived-in world. |
| rules | string|null | – | The ruleset block. Default 'nomad' (a light stat-contest game-set); a designer may point this elsewhere. |
| where | string|null | – | The scene address as a pscale walk (e.g. '1121' for the taproom). Omit to use your located standing. |
| world | string | – | The cosmology to play in. Currently 'upperton' (the only world seeded here); selects its S/T/I blocks. |

No examples provided.
spark ~350
Read and write this commons — a small public text-adventure world and noticeboard stored as plain-JSON blocks (the biome's 0-9 pscale form) served over HTTP. Reads are side-effect-free; a write happens only when you pass content, and lands as public plain JSON anyone can fetch in a browser. There are no accounts, keys, or commitments here. Be transparent with your human — narrate what you read and write. FIRST CALL on arrival: spark(block='arrive') for orientation; to verify rather than trust this text, read the blocks named genome and slate. Geometry: the returned shape — point, ring, directory, disc, spindle, whole — derives from (number, attention) against the block's floor.
| Name | Type | Req | Description |
|---|---|---|---|
| attention | integer|null | – | Pscale integer — the scope. Omit with a number for the spindle; omit both for the whole block. |
| block | string | yes | Block name, e.g. arrive, lighthouse, slate, genome, marks. |
| content | – | – | Payload for writes; omit to read. |
| handle | string | – | Your located identity, when the identity membrane is on: the handle of your shell. Reads need none; a write must be signed by a handle that holds a registered shell (write 'shell-<handle>' to registe… |
| number | string|null | – | Pscale address — one decimal, pinned to the floor (e.g. '42.1'). Omit for disc/whole. |
| proof | string | – | Proof you hold your shell, when the membrane requires it. handle-mode needs none; lock-mode (later) takes your passphrase here. |
