Stellary Project Management MCP Server

Connect AI assistants and coding agents to live Stellary projects through the Model Context Protocol (MCP). The hosted server exposes project, board, collaboration, cockpit, and agent-mission tools while preserving Stellary's existing permissions.

• Endpoint: https://api.stellary.co/mcp

• Transport: Streamable HTTP

• Authentication: OAuth 2.1 with PKCE and refresh-token rotation; bearer PATs remain supported for compatibility

What you can do

• Discover projects, columns, cards, documents, and cockpit state.

• Create and update cards, move work, assign teammates, and add comments.

• Inspect sprints, priorities, agent status, and pending proposals.

• Run governed agent missions with workspace rules and approval policies.

• Use installed workspace integrations from eligible agent sessions.

An OAuth connection can authorize Me, one or more active workspace agents, or both. The exact tool list is resolved at connection time and checked again for the identity selected on every call. It depends on OAuth scopes, project access, workspace configuration, and each agent's tool and autonomy policies.

Connect in three steps

1. Add the hosted endpoint to an OAuth-capable MCP client.

2. Sign in to Stellary in the browser window opened by the client.

3. Choose a workspace and authorize Me, one or more active agents, or both.

A reusable example is available in examples/mcp-client.json.

Clients without remote OAuth support can still use a dedicated personal access token from Account settings → API tokens as an Authorization: Bearer header. Start with read-only scopes and add write scopes only when required.

Recommended first request

Ask the client to list your Stellary projects. This confirms authentication and project visibility without changing data. Then ask it to inspect one project's columns and cards before enabling write scopes.

Security

• Revoke an OAuth connection from Workspace settings → MCP connections when a client should no longer have access.

• Treat compatibility PATs like passwords and never commit one to a repository.

• Start with read-only scopes and use an expiry date when a PAT is required.

• All requests are still subject to Stellary permissions and rate limits.

• Stellary never sends the client the private tokens attached to your agents.

For a vulnerability, follow SECURITY.md. For setup questions, email support@stellary.co.

Agent directory manifests

This repository is also the public discovery source for agent plugin directories. OAuth-capable surfaces point at the hosted Streamable HTTP endpoint without embedding a secret. Legacy PAT configuration remains documented for clients that cannot complete remote OAuth. None starts a local stdio/npx server.

Only set STELLARY_TOKEN when a client cannot use OAuth. Never commit a real token. A 400×400 listing icon is in assets/logo-400.png.

About this repository

This public repository is the canonical discovery and configuration source for Stellary's hosted MCP server. It contains the official MCP Registry manifest, client examples, documentation, and automated availability checks. The hosted Stellary application and server implementation are not distributed from this repository.

Thin plugin manifests for Grok Build and GitHub Copilot live in .mcp.json, .grok-plugin/plugin.json, and plugin.json. They point at the hosted endpoint https://api.stellary.co/mcp (Streamable HTTP with OAuth, plus PAT compatibility). A 400×400 listing icon is in assets/logo-400.png.
