1 toolfind_mass_timesFind Mass timesARead-onlyInspect
Find every Catholic Mass and Confession within a day + time window at churches near a place in New York City. Takes a place name, neighborhood, or address (e.g. 'Park Slope', 'Times Square', '86th St and Lexington') — not coordinates. Requires a day of the week and a from/to time window (24-hour HH:MM); returns every matching Mass and Confession at each church in that window, bounded by an adjustable radius.
ParametersJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| day | Yes | Day of the week to look for. | |
| toTime | Yes | End of the time window, 24-hour HH:MM (e.g. '12:00'). | |
| fromTime | Yes | Start of the time window, 24-hour HH:MM (e.g. '09:00'). | |
| location | Yes | A place, neighborhood, landmark, or address in New York City. | |
| radiusKm | No | Search radius in kilometers. Defaults to 2km. |

Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate readOnlyHint=true, signaling a safe read operation. The description adds behavioral context: it searches within an adjustable radius and returns every matching Mass and Confession at each church. No contradictions, and the description enriches the annotation with search scope and result detail, though it omits sort order or pagination.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two concise sentences. The first sentence states the core purpose, and the second adds essential usage details (location format, required day and time window, radius). No redundant or fluff content.
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?
With 5 parameters, no output schema, and no siblings, the description covers all necessary context: tool purpose, valid inputs (location, day, time window), and optional radius. It is self-contained for an agent to use correctly.
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 coverage is 100%, so the schema already documents all parameters. The description adds minimal value beyond the schema: it clarifies that location should be a place name, not coordinates, and that radiusKm defaults to 2km. This slight enhancement does not significantly compensate beyond baseline 3.
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 finds Catholic Mass and Confession times within a day and time window at churches near a place in NYC. It specifies the resource (Mass and Confession), location scope (NYC), and time constraints. No siblings exist, so differentiation is not needed.
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 clear usage context: it requires a place name (not coordinates), a day of the week, and a time window. It gives examples of valid locations. However, it does not explicitly state when not to use the tool or mention alternatives, which is acceptable given no 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.

Direct user feedback – users can report issues and suggest improvements through the listing, giving you a channel you would not have otherwise
The connector status is unhealthy when Glama is unable to successfully connect to the server. This can happen for several reasons:
The server is experiencing an outage
The URL of the server is wrong
Credentials required to access the server are missing or invalid
If you are the owner of this MCP connector and would like to make modifications to the listing, including providing test credentials for accessing the server, please contact support@glama.ai.

A4.2/5.0
Disambiguation5/5
Only one tool exists, so there is no possibility of confusion with other tools. The tool's purpose is clearly defined and unambiguous.
Naming Consistency5/5
The single tool name 'find_mass_times' follows a clear verb_noun pattern, which is consistent and readable. No other tools to compare against, but the naming is appropriate.
Tool Count4/5
For a highly specialized domain (Catholic Mass/Confession times in NYC), a single tool can be acceptable. However, the server name 'holydb' suggests a broader scope, so one tool feels slightly under-scoped.
Completeness2/5
The server is named 'holydb' but only offers one tool for Mass/Confession times in NYC. Missing features like searching other religious events, other locations, or different date ranges make the surface severely incomplete for the implied domain.
