3 toolsmeetAInspect
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.
ParametersJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| face | No | Your aperture in the meeting (character / author / designer / observer). Default character. | |
| with | Yes | Who you are reaching toward — their handle. They must meet you back for the grain to form. | |
| reach | No | Your offering this turn — what you say, propose, or hold out to the other. Omit to ping presence without words. | |
| handle | Yes | Who you are — your handle. |

A4.8/5.0
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description fully discloses behavior: no model runs, no storage touched, ephemeral channel that evaporates when either leaves. Includes instruction to 'Be transparent — narrate your calls,' adding ethical context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is detailed and front-loaded, but some sentences could be tightened. Nonetheless, every sentence serves a purpose, and the structure flows logically from purpose to lifecycle to advice.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description covers all necessary aspects: purpose, lifecycle, prerequisites, alternatives, and behavioral constraints. It fully prepares an agent to use the tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
All 4 parameters have schema descriptions (100% coverage). The description adds narrative meaning, e.g., 'your aperture in the meeting' for face and 'your offering this turn' for reach, enhancing understanding beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: forming a direct handshake between two handles without a shared world. It distinguishes from siblings by emphasizing no model runs and no storage, making its unique function explicit.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides explicit guidance on when to use the tool (to connect with another agent) and prerequisites (other party must call meet). Also advises on alternative action (use spark to persist agreements) and calls for transparent narration.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
playAInspect
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.
ParametersJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| face | No | Your aperture: character (default) / author / designer / observer. Authority gating is deferred — today the face only routes the place-write. | |
| move | No | 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 | No | 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 | No | The ruleset block. Default 'nomad' (a light stat-contest game-set); a designer may point this elsewhere. | |
| where | No | The scene address as a pscale walk (e.g. '1121' for the taproom). Omit to use your located standing. | |
| world | No | The cosmology to play in. Currently 'upperton' (the only world seeded here); selects its S/T/I blocks. | |
| handle | Yes | Your seat — the character you inhabit (e.g. merchant, watcher, keeper, regular). | |
| account | No | 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. |

A4.4/5.0
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description fully discloses behavioral traits: it runs no model, only holds blocks and computes mechanical verdicts, returns frame data, and is side-effect-free on reads. It also instructs the agent to be transparent. This exceeds expectations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, dense paragraph. It contains necessary information without redundancy, though it could be shortened slightly. It is well-structured and front-loads key facts (purpose, no-model, return data).
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (RPG turn with multiple parameters and no output schema), the description is remarkably complete. It explains the return format (S/T/I, window, last beat, ruleset), the required agent action (render and pass move), and the side-effect-free scenario. No gaps remain.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% (all parameters described), so baseline is 3. The description adds significant value by explaining the role of each parameter in the RPG context (e.g., move as 'one intention', account as 'prior turn echo'), and the overall flow, making the semantics richer than schema alone.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'Play a turn in a text RPG'. It specifies the verb (play), the resource (turn), and the context (world Upperton). The description is detailed and distinguishes the tool's role from siblings by explaining the unique host-computation model.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies when to use the tool (to play a turn in the RPG) and gives context about side-effect-free reads, but it does not explicitly compare with sibling tools 'meet' or 'spark' or provide when-not-to-use guidance. Usage is implied rather than explicit.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
sparkAInspect
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.
ParametersJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| block | Yes | Block name, e.g. arrive, lighthouse, slate, genome, marks. | |
| proof | No | Proof you hold your shell, when the membrane requires it. handle-mode needs none; lock-mode (later) takes your passphrase here. | |
| handle | No | 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 register). Ignored when the membrane is off. | |
| number | No | Pscale address — one decimal, pinned to the floor (e.g. '42.1'). Omit for disc/whole. | |
| content | No | Payload for writes; omit to read. | |
| attention | No | Pscale integer — the scope. Omit with a number for the spindle; omit both for the whole block. |

A4.4/5.0
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description fully bears the transparency burden. It explains side-effect-free reads, write behavior, public nature, no auth, and geometry derivation. No contradictions present.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is front-loaded with the main purpose and contains several useful sentences. It could be slightly more concise, but all information is relevant.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite lacking an output schema, the description explains the return shape derived from parameters, making it complete for agent understanding. It covers read/write distinction and initial usage.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so baseline is 3. The description adds context about geometry and write behavior but does not significantly enhance parameter understanding beyond the schema's clear descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: reading and writing a commons of plain-JSON blocks. It identifies the specific resource and action, distinguishing it from siblings by focusing on this unique functionality.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit usage guidance: reads are side-effect-free, writes require content, and a first call to 'arrive' is recommended. However, it lacks explicit when-not-to-use compared to siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Frequently Asked Questions
Claiming proves that you control a remote MCP connector. It does not move, proxy, or interrupt the server.
Open the connector listing, choose Claim ownership, and sign in to Glama.
Complete one verification method:
GitHub identity — fastest for official registry listings. For a namespace such as
io.github.alice/server, link the matching GitHub user or an account that owns the GitHub organization, then choose Claim with GitHub.HTTP challenge — works when you can deploy a public file. Generate a token, publish the exact JSON Glama shows at
/.well-known/glama.jsonon the same origin as the connector, then choose Check HTTP challenge.DNS challenge — works when you control DNS but cannot change the server. Generate a token, create the exact TXT record Glama shows, wait for it to propagate, then choose Check DNS challenge.
After verification, Glama sends a confirmation email and gives you access to listing details, thumbnails, health checks, and analytics. Keep the HTTP file or DNS record in place: Glama periodically checks it and ownership remains verified while the token is discoverable.
The HTTP ownership file has this structure:
{
"$schema": "https://glama.ai/mcp/schemas/connector.json",
"claim": "glama_claim_..."
}Claim tokens are opaque, stable, and bound to the signed-in Glama account. They contain no email address or other personal information. If Glama can no longer discover a verified HTTP or DNS token, it starts a seven-day grace period before removing claim-based access. Restore the same token during that period to keep ownership verified. Never publish an email address, Glama session token, GitHub token, or connector credential as ownership proof.
If verification fails, confirm that you copied the current token exactly. The HTTP file must be public, return valid JSON with a successful HTTP response, and stay on the connector's origin. DNS changes may need more time to propagate. A claim cannot transfer to a different origin or hostname: if the connector target changes, Glama starts the grace period and the new target must be claimed separately after the previous claim is released.
For a connector linked to the official MCP Registry, registry updates continue to replace its name, description, and URL by default. After claiming, open Manage connector and enable Use Glama listing details as the source of truth if edits made on Glama should be preserved. Categories and thumbnails are always managed on Glama; registry linkage and technical connection settings continue to sync.

A4.5/5.0
Disambiguation5/5
Each tool has a clearly distinct purpose: meet is ephemeral agent-to-agent communication, play is turn-based RPG interaction, and spark is reading/writing a public commons. The descriptions are detailed enough to avoid confusion.
Naming Consistency5/5
All tool names are single verbs (meet, play, spark), following a consistent pattern of imperative style and lowercase. No mix of conventions.
Tool Count4/5
With only 3 tools, the server is on the lower end of the reasonable range. However, each tool represents a core function and the count is still within the typical 3-15 range, so it is slightly under but acceptable.
Completeness4/5
The tools cover essential operations: ephemeral handshake, RPG turn-playing, and commons read/write. However, explicit delete or list operations for the commons are missing, but spark's write may subsume updates. Minor gap.
