kynth-mcp

MCP server from Kynth Studios. Ten read-only lookup tools backed by live public data — no API key, no signup, nothing to sign up for.

mcp-name: studio.kynth/kynth-mcp

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.

Tools

Things that go stale

| Tool | Answers | | --- | --- | | compare_ai_models(board?, limit?) | Current AI model pricing and which models the major coding tools actually route to, sampled nightly. Boards by budget band (budget/free … budget/premium) or by tool (tool/claude-code, tool/codex-cli, tool/cline, tool/aider, …). Ranked on adoption, not capability — each row carries the rationale that says so. | | check_project_maintenance(q?, limit?) | Whether a developer tool is still shipping: last release, last commit, whether it reads as dead. Run it before recommending a dependency. | | lookup_service_pricing(category?, service?) | Published pricing and free-tier limits for auth, database, payments, email and hosting services — each plan carrying the date its published price was last verified against the vendor's own page. | | estimate_stack_cost(stack, users?) | An itemised monthly bill for a named stack at a chosen user count, showing which lines are included in the base fee and which are metered. |

Directories

| Tool | Answers | | --- | --- | | search_agent_skills(q, kind?, limit?) | Published Claude Code skills, plugins and marketplaces, ranked by installs. Returns the install command, so the answer is directly actionable. | | search_agent_configs(stack?, format?, tag?, …) | Real AGENTS.md, CLAUDE.md, Cursor, Copilot, Windsurf, GEMINI.md and Cline files from public repositories, scored for quality — how well-maintained projects on a given stack actually write theirs. | | search_component_registries(q, kind?, limit?) | shadcn-compatible components, blocks and hooks across dozens of public registries, with their dependencies so you can judge the cost of pulling one in. | | grade_starter_kit(q?, limit?) | Starter kits and boilerplates, graded by installing them: what is actually wired up versus what only appears in the README. |

Compliance

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.
