kynth-mcp
This server provides two read-only lookup tools for public data: one for checking US local government website accessibility under ADA Title II, and another for checking nonprofit tax-exempt status and California fundraising compliance.
Look up ADA Title II website accessibility reports (
lookup_ada_report): Given a.govdomain, returns an accessibility grade (A–F), WCAG 2.1 AA violation counts (total, serious, critical), top failing rules, ADA Title II compliance deadline (April 2027 for communities 50,000+, April 2028 for smaller), and a link to the full public report on civicbinder.org.Look up nonprofit IRS/California good standing (
lookup_nonprofit_status): Given an EIN, checks the IRS auto-revocation list and California Registry of Charities delinquency/suspension lists. Returns revocation/reinstatement dates, whether the streamlined 15-month reinstatement window is open, and whether AB 488 requires blocking donations. Aclear: trueindicates no issues found.
No API key or signup needed; uses live public data.
Provides a tool for evaluating whether apps built by AI mobile-app builders will clear Apple App Store review, covering output details, source exportability, binary submission, and applicable guidelines.

Most of these answer questions that a model cannot answer correctly from a training cutoff, because the underlying fact changed after it: what a model costs today, whether a library is still maintained, whether someone has already published the skill you are about to write.

lookup_ada_report(domain)
Looks up a US local-government domain in the CivicBinder Municipal Web Accessibility Index — axe-core scans of local-government .gov websites, graded A–F against WCAG 2.1 AA ahead of the ADA Title II deadlines (April 26, 2027 for communities of 50,000+; April 26, 2028 for smaller communities and special districts).
Returns the grade, violation counts (total / serious / critical), the top failing rules, the entity's deadline, and the public report page (https://civicbinder.org/ada/<domain>). The full index is also published as an open dataset at civicbinder.org/ada/dataset.json.
lookup_nonprofit_status(ein)
Checks a nonprofit's EIN against the IRS auto-revocation list and the California Registry of Charities delinquency/suspension lists, via GoodStanding. Returns revocation and reinstatement dates, whether the streamlined 15-month reinstatement window is still open, and whether AB 488 requires charitable fundraising platforms to block the organization's donation pages. A clear: true result means the EIN is on none of the tracked lists.

Available Tools
2 toolslookup_ada_reportLook up an ADA Title II website accessibility reportA
Look up a US local-government (.gov) domain in the CivicBinder Municipal Web Accessibility Index. Returns the accessibility grade (A-F), WCAG 2.1 AA violation counts from an axe-core scan, the failing rules, the entity's ADA Title II compliance deadline (April 2027 or April 2028), and a link to the full public report page. Use for questions like "is cityofx.gov ADA compliant" or "how accessible is this county website".
| Name | Required | Description | Default |
|---|---|---|---|
| domain | Yes | The .gov domain to look up, e.g. "denvergov.org" or "cityofmadison.com". Protocol and paths are stripped automatically. |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden. It discloses what the tool returns in detail and implies a read-only operation via the verb 'look up'. It doesn't mention error handling for domains not in the index, but this is minor for a lookup tool.
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 description is tightly written: it leads with the action, summarizes the return payload, gives example questions, and includes the protocol-stripping note. Every sentence earns its place without 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?
For a single-parameter lookup with no output schema, the description fully covers what the tool does, what it returns, and when to use it. It is self-contained and sufficient for an agent to invoke the tool correctly.
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?
The schema already fully documents the single parameter. The description adds valuable behavior beyond the schema, noting that protocol and paths are stripped automatically, which helps the agent construct valid input.
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 states the specific verb 'look up' and the resource 'CivicBinder Municipal Web Accessibility Index', and lists the specific return fields (grade, violation counts, failing rules, deadline, link). It clearly differentiates from the sibling tool lookup_nonprofit_status, which is about a different subject entirely.
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?
Provides clear usage context with example questions ('is cityofx.gov ADA compliant') and explicit scope (.gov domains). It doesn't explicitly state when not to use it, but the sibling tool is obviously different in domain, so the guidance is adequate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
lookup_nonprofit_statusLook up nonprofit IRS / California good standing by EINA
Check a US nonprofit's standing by EIN against the IRS auto-revocation list (tax-exempt status revoked for three consecutive missed Form 990 filings) and California Registry of Charities delinquency/suspension lists. Returns revocation and reinstatement dates, whether the streamlined 15-month reinstatement window is still open, and whether AB 488 requires fundraising platforms to block donations. A "clear" result means the EIN is on none of the tracked lists.
| Name | Required | Description | Default |
|---|---|---|---|
| ein | Yes | The organization's 9-digit EIN, with or without a dash, e.g. "12-3456789". |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It discloses key behavioral details: the data sources checked, the types of returned information, and the meaning of 'clear'. It does not mention any limitations, caching, or error conditions, but for a lookup tool this is quite transparent.
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 description is concise and front-loaded: two sentences, the first stating the main action and data sources, the second defining the key result. Every sentence adds value, with no fluff or repetition.
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?
For a tool with one parameter, no output schema, and no annotations, the description is complete: it identifies the exact lists, the return values, and the meaning of a clear result. It gives the user sufficient understanding without needing to guess return structure or side effects.
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?
The schema covers 100% of the parameter 'ein' with a description and example. The tool description mentions 'by EIN' but adds no new meaning beyond the schema. Thus the baseline score of 3 applies; the description does not need to compensate for schema coverage.
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 clearly states the tool checks a US nonprofit's standing by EIN against specific IRS and California lists, enumerating exactly what is checked (auto-revocation, delinquency/suspension) and what is returned (dates, reinstatement window, AB 488 effect). This distinguishes it from the sibling lookup_ada_report and uses a specific verb ('Check') with a well-defined resource.
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?
The description provides clear context about the tool's scope (IRS and California lists) and what constitutes a 'clear' result, but it does not explicitly state when to use this tool versus alternatives or any exclusions. Since the sibling tool is not referenced, it lacks explicit when-not-to-use guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Scored across 2 tools
The two tools are completely distinct: one checks government website accessibility, the other checks nonprofit tax status. There is no overlap or ambiguity between them.
Both tools follow the exact same 'lookup_*' pattern with a clear noun, making the naming consistent and predictable.
With only two tools, the server is slightly under the typical range, but each tool addresses a specific, well-defined lookup need, so the count is reasonable for a niche server.
Each tool fully covers its intended lookup scenario (accessibility report and nonprofit status). No obvious missing operations exist for the stated purpose, though the overall scope is limited.
