About Vinktar

Vinktar connects coding agents to error tracking data and the user actions preceding errors. Its MCP server, setup skill, and command support project setup and questions about errors, releases, and affected users.

Key features

  1. 01Read errors and preceding user actions
  2. 02Ask questions about error and release trends
  3. 03Set up project instrumentation with a skill
  4. 04Check that incoming data is received
  5. 05Control access by workspace and project

Use cases

  1. 01Find errors following a recent deployment
  2. 02Identify errors affecting the most users
  3. 03Instrument a repository and verify incoming events
  4. 04Review changes in error trends over a week

MCP support

Exposes Vinktar workspace and project data to MCP clients through `https://mcp.vinktar.com/mcp`, using browser sign-in and scoped permissions. The accompanying setup skill and `/vinktar` command help agents configure projects and query error data.

Configuration

Remote servers need no local install. Pick your client, then copy the config or install in one click.

From the project README

Vinktar for coding agents

Vinktar is error tracking your coding agent can read, with what the user did right before each error. This plugin gives Claude Code, Cursor and Codex three things:

  • The Vinktar MCP server (https://mcp.vinktar.com/mcp). You sign in in the browser and choose a workspace, the projects it may reach, and read, build or configure. No key to paste.
  • The setup skill. Run /vinktar:setup in Claude Code, or ask your agent to "set up Vinktar". It reads your repo, installs the SDK for your stack in a standard layout, fetches the project's write key over the connection, wires identify, errors and source maps, defines each event it tracks, checks what actually arrived, and ends with a list of every environment variable and where it goes.
  • The /vinktar command. Type /vinktar to set Vinktar up in this repo, or once it is set up to hear what broke. /vinktar what broke after the last deploy? asks a question directly.

Once it's installed, ask it things like "what changed this week?" or "which errors hit the most people since the last release?".

You don't need an account beforehand. Before anyone signs in, the agent can start a project on its own (start_project), set the app up with its key and check that data arrives; you then open the claim link it gives you, which signs you in or makes your account and keeps the project with its data. Unclaimed, a project takes up to 10,000 events and is deleted with its data after 7 days.

Install

Claude Code

claude plugin marketplace add vinktarhq/agent
claude plugin install vinktar@vinktar

Run /vinktar:setup. It can set the app up before you sign in; to ask questions about your data later, run /mcp, pick vinktar and authenticate.

Claude (claude.ai, the desktop app, Cowork)

Adding the plugin does not connect Vinktar. After you add it:

  1. Open the plugin's Connectors tab, or claude.ai/customize/connectors, and choose Connect next to Vinktar.
  2. Sign in or make a free account in the browser, leave Build and Configure on, and approve.
  3. Start a new chat. A chat that was already open does not pick up the connection.

Then ask "what broke today?", or type /vinktar.

Cursor

Import this repository under Customize → Plugins → From GitHub Repository. Cursor asks you to sign in the first time it connects.

Codex

codex plugin marketplace add vinktarhq/agent
codex plugin add vinktar@vinktar
codex mcp add vinktar --url https://mcp.vinktar.com/mcp

The last line adds the connection and opens the sign-in in your browser.

Any other MCP client

Add https://mcp.vinktar.com/mcp as a Streamable HTTP server; it finds the sign-in on its own. Then ask your agent to call get_install_guide. Setup for each client: vinktar.com/docs/mcp.

A harness that reads skills but has no plugin format

Copy .agents/skills/setup/ into your repository (or your home directory, wherever your tool looks). It is the same skill, at the path most tools agree on, and it needs the MCP server added separately.

What it can and can't do

The agent sees what you'd see in the workspace and project you approved. The only things it can delete are boards and panels, and those stay restorable from the boards page for 30 days. It can't delete events, errors, issues or projects, create projects or keys once you are signed in, manage members or billing, or add somewhere new to send your data. Before sign-in it can start one project nobody owns until you claim it. Every call is logged on the project's AI agents page, and an admin can switch agents off.

Vinktar works on every plan, Free included. Data requests count against a monthly allowance; setting a project up never does, and nothing is charged per call.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
