Do I need credentials to use this MCP?

No. The Vinkius catalog is fully public. All search, browse, and detail operations work without any credentials.

What data does the search return?

Search returns MCP cards with title, description, slug, tool count, debugger quality grade, and auth requirement. Results are ranked by relevance using AI-powered keyword extraction.

Can I filter by category and server type simultaneously?

Yes. All filter parameters (category, tag, server_type) can be combined in both search and browse operations for precise results.

What does the debugger grade mean?

Each MCP is scanned by the Vinkius Debugger, which grades quality from A (excellent) to F (critical issues). The grade reflects tool schema compliance, error handling, response consistency, and documentation completeness.

More Details Connect to Claude

Turn your AI agent into a catalog intelligence operator with Vinkius MCP Catalog. This integration gives agents direct, programmatic access to every MCP in the Vinkius catalog — the largest curated collection of MCP integrations for autonomous AI agents.

Your agent can search the catalog using natural language, browse by category or tag, inspect individual MCPs with full detail (tools, debugger grade, FAQs, prompt examples), and monitor catalog growth through real-time statistics.

What you can do

Catalog Search — Find MCPs using natural language queries. The Vinkius search engine uses AI-powered keyword extraction and PostgreSQL full-text search with relevance ranking.
Browse & Filter — Navigate the catalog by category, tag, or server type (API, Skills, Vurb).
MCP Analysis — Inspect any MCP's complete profile: exposed tools, FAQs, debugger quality grade, trust score, prompt examples, and full Markdown documentation.
Category Intelligence — Explore the full taxonomy of featured and organic categories, each with real-time MCP counts.
Tag Discovery — Audit every tag in the catalog with MCP frequency data.
Catalog Stats — Monitor catalog growth with live count metrics.

12 tools expose this connector's capabilities to your AI agent.

get_connect_token

Returns {mcp_url, source: owner|subscription|preview}. mcp_url embeds a secret token. Get the ready-to-use connection URL for an MCP

credentials_status

Returns credentials_configured (+oauth_status when applicable). Check whether an MCP is ready or missing credentials

get_credentials_schema

Returns credential_schema + credentials_configured. Feed the field keys into set_credentials. Credential VALUES are user-owned secrets: never invent, guess or fabricate them — if you do not hold the real value, say what is missing instead of filling the schema. Get the credential fields an MCP needs

get_listing_faqs

Returns {faqs: [{question, answer}]}. Read a catalog MCP's FAQs

get_listing_prompts

Returns {prompt_examples: [{prompt, response}]}. See example prompts for a catalog MCP

get_listing

search_catalog already returns each MCP's tools — use this only for FAQs, prompt examples, or related MCPs. Prompt examples show the expected flow: read them before driving an MCP you have never used. Deep detail of one catalog MCP: description, FAQs, prompt examples, related

get_random_listings

up to 10 MCPs]}, rotating every 60 seconds. Sample random installable MCPs. For a specific need, use search_catalog

invoke_tool

Fails if the MCP needs credentials or is not connected — fix with credentials_status + set_credentials first. A failed invocation is feedback, not a dead end: the error text names the contract that was violated; adjust arguments or read the schema again instead of repeating the same call. Run one tool on an MCP you have, executed by Vinkius

active_mcps

server_id feeds every account tool below. List the MCPs you own or have installed

list_tools

Returns {tools: [{name, description, inputSchema}]}. Tool names and schemas are in English: read the inputSchema before the first invocation of a tool — never guess argument names or types. If that MCP still needs credentials, its tools will fail until set_credentials runs. List an MCP's tools with their argument schemas

search_catalog

Requires a free Vinkius account — anonymous calls fail with the connect URL. Use the catalog first for external capabilities. Results already include the matching servers and their tools, descriptions, and input schemas. Refine weak searches before concluding no suitable capability exists. Search the Vinkius catalog for capabilities the agent can use across apps, services, data sources, devices, AI tools, and automations

set_credentials

Values must come from the user or an existing vault — never fabricate or guess one; a wrong value surfaces later as tool failures that look like connector bugs. Save an MCP's credentials so its tools work
