Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds the 'app-only unseen-frame' and 'mounted widget' constraints, which are useful behavioral boundaries, though it does not explain what 'unseen-frame' means or how afterSequence affects state.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The one-sentence description is brief and front-loads 'App-only unseen-frame reader', but it sacrifices needed semantics for brevity and is closer to under-specification than disciplined conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite an output schema and annotations covering read-only behavior, the description leaves key invocation semantics unexplained: neither parameter is documented, the 'unseen-frame' contract is undefined, and the sibling render_information_ui is not referenced. An agent cannot reliably select or invoke this tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the description says nothing about runId or afterSequence. The agent is left to infer that runId identifies a run and afterSequence is a numeric cursor, with no help from the tool definition.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description identifies a reader for an information UI run and adds scope ('app-only unseen-frame', 'mounted Fify widget'), but relies on unstated jargon and does not clearly differentiate from the sibling render_information_ui beyond the word 'reader'. It is more specific than a tautology, yet an agent cannot confidently know what operation this performs.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No usage guidance is provided. There is no statement of when to call this tool versus render_information_ui, no prerequisites such as Fify widget mounting, and no conditions around unseen-frame reads.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
render_information_uiRender information as an interactive viewARead-onlyInspect
Render a fully grounded answer as a non-consequential interactive information view when structure or interaction materially improves it. Complete factual reasoning first and always pass the authoritative plain answer. If the user supplied sufficient facts, use them directly and invoke immediately without extra retrieval. For a named real-person profile, set profileSubject to the canonical name unless the user requests no image; Fify will perform a bounded trusted Wikimedia portrait lookup. Pre-resolved attributed Wikimedia or Openverse media may also be supplied, but never invent or guess media URLs.

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already carry the safety profile (readOnlyHint=true, openWorldHint=true, destructiveHint=false), so the description's 'non-consequential' claim is aligned but not additive on safety. It adds genuine behavioral disclosure beyond annotations: 'Fify will perform a bounded trusted Wikimedia portrait lookup' for named real-person profiles, plus the trust boundary of never inventing media URLs. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Five dense sentences, roughly 110 words, with the core purpose front-loaded and workflow/constraints following in logical order. Every sentence earns its place: trigger condition, reasoning sequence, immediate-invocation rule, profileSubject procedure, media constraint. No filler or redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
An output schema exists, so return-value documentation is unnecessary. The description, schema, and annotations together cover the invocation trigger, grounding workflow, profile-image behavior, and media provenance constraints. Minor gaps remain around the role of continuationState and originalRequest, but these are inferable from their names and the sibling read tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is only 10%, so the description must compensate. It does add real parameter guidance for profileSubject (set to canonical name unless no image requested), media (pre-resolved Wikimedia/Openverse only, never guess URLs), and groundedAnswer (always pass the authoritative plain answer). However, required params like originalRequest, continuationState, and suggestedRefinements receive no semantic enrichment, leaving part of the burden unmet.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description opens with a specific verb+resource+condition: 'Render a fully grounded answer as a non-consequential interactive information view when structure or interaction materially improves it.' This names the deliverable (interactive view), the input (grounded answer), and the trigger condition, and it is clearly distinguished from the sibling read_information_ui_run by the render-vs-read contrast.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Usage context is explicit and actionable: invoke 'when structure or interaction materially improves it', complete factual reasoning first, always pass the authoritative plain answer, avoid extra retrieval when sufficient facts are supplied, and never guess media URLs. It tells the agent not just what to do but the order in which to do it.
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, then choose Claim with GitHub. An organization namespace such asio.github.acme/serveralso needs that organization to have installed the Glama AI GitHub App and approved its permissions, because GitHub discloses organization membership only to apps it has installed. Use HTTP or DNS when it has not.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.

The two tools are distinct in action: one reads the mounted widget's frames, the other renders an information view. However, both share the 'information_ui' terminology, and the cryptic 'read_information_ui_run' naming could cause some initial confusion about where the boundary lies.
Both names start with a verb and use snake_case, but 'render_information_ui' follows a clean verb_noun pattern while 'read_information_ui_run' adds an awkward '_run' suffix. This minor inconsistency suggests a mixed convention that is still readable.
With only two tools, the set feels thin for a general-purpose information UI server, but it may be appropriately scoped for a tightly coupled widget with read and render capabilities. The tools each seem to serve a distinct role, making the small count borderline rather than clearly deficient.
For the apparent domain of managing a Fify information widget, providing a read mechanism and a render mechanism covers the core lifecycle. The render tool also incorporates fallback behaviors like profile lookups and media handling, suggesting the surface is reasonably complete for its narrow scope.
