Three of the most-used PM tools (Asana, ClickUp, and Linear) now all ship official MCP servers. If you're picking one, or evaluating whether your existing PM tool is the right one for an agent-driven workflow, the differences matter more than the marketing pages suggest. Here's how they actually compare.

Surface area

ClickUp wins this on volume alone. The official server exposes roughly 49 tools across 14 categories: search, task management, bulk operations, attachments, comments, tags, relationships, task movement, time tracking, workspace hierarchy, members, chat, docs, and time-in-status. If you want an agent doing real work in your PM tool rather than just reading from it, ClickUp's MCP is closer to "your full PM API" than the others.

Asana sits in the middle. The Work Graph access covers tasks, projects, teams, sections, custom fields, comments. Everything you'd expect from a daily Asana user's surface. Less broad than ClickUp but more enterprise-aware (workspace admin gating, permission-scoped access).

Linear is the leanest. The MCP focuses on issues, projects, teams, and search. Linear's whole product philosophy is "fewer features done well," and the MCP follows that pattern. If you're a Linear user you'll find the surface matches the tool. If you're hoping for chat or doc operations, they're not there.

Install and auth

All three follow the same modern pattern: remote server, Streamable HTTP transport, OAuth via browser, no API token to copy. The install command varies but the shape is identical:

claude mcp add asana --transport http https://mcp.asana.com/v2/mcp
claude mcp add clickup --transport http https://mcp.clickup.com/mcp

Linear's official MCP is published as an npm package and runs locally rather than remote: npx -y @linear/mcp. The reason is historical (Linear's MCP predates Streamable HTTP being widely supported), but the practical difference is you need a Linear API key, not OAuth.

Workspace gating

Asana requires the MCP to be unblocked under workspace admin's app management settings. For teams with locked-down third-party integrations, that's an approval flow you'll need to navigate. ClickUp and Linear don't have an equivalent gate at the workspace level. If you can authenticate, you're in.

Known issues

ClickUp has documented bugs around task creation with assignees and custom fields, plus OAuth persistence in automation contexts. None are blockers for interactive use; some are blockers for scripted workflows.

Asana's MCP is the newest of the three and has rough edges in less-common Work Graph queries (multi-team filters, complex custom field combinations).

Linear's MCP is the most mature and has the fewest reported issues, partly because its surface is smallest.

Which one

For solo users and small teams: pick whichever one your team already uses. The MCP doesn't change the underlying tool, and switching PM tools for the MCP is the tail wagging the dog.

For new teams choosing fresh: Linear if you value lean, opinionated tooling. ClickUp if you want the deepest agent integration surface available right now. Asana if you need enterprise admin controls baked in.

For teams considering agent-driven automation specifically: ClickUp's surface area is the differentiator. The bulk operations alone justify the integration for any team doing weekly triage at scale.

For everyone: connect the official one, not a community wrapper. Vendor-maintained MCPs get the bug fixes; community wrappers don't.

What's missing across all three

None of them currently expose anything close to "explain why this estimate was changed" or "what was discussed in this task's history." Task history exists in the underlying tools, but the MCP surfaces are forward-looking (do work) rather than backward-looking (understand work). For agent handoff in PM contexts, this is the actual gap.
