Planhat MCP

Talk to your Planhat customer data in plain English.

Struggling to make Planhat's hosted MCP work? Custom connector in Claude that won't connect, or an OAuth login that never completes once it does?

Here's your answer: a Model Context Protocol server for Planhat that runs on your own machine and authenticates with a plain API token. No OAuth flow, no connector setup, nothing to host. Add it to Claude Desktop or any other MCP client and ask for what you need:

"Which companies have licenses renewing this quarter?"

"Create a task for me to follow up with Acme Corp next week."

"Summarize the open tickets for our top five accounts."

Claude reads and updates Planhat directly, live from the conversation. No dashboards, no exports, no SQL.

It runs entirely on your own computer, with your own Planhat API token. No third-party service sits between your AI and your customer data.

Install in Claude Desktop

Download one file, double-click it, paste your token. No terminal, no config files, no code, and nothing to install first.

1. Download the .mcpb file.
2. Double-click the downloaded file. Claude Desktop opens an install pop-up.
3. Review the pop-up and click Install.
4. Create a Planhat API token if you don't have one: in Planhat, go to Settings > Service Accounts (Private Apps) > API Access Token. Admin access is required.
5. Paste the token into the token field. It is stored in your system keychain, never in a file on disk.
6. Optional: tick Read-only mode or Disable delete tools to limit what the AI can do.
7. Ask Claude: "List my top 3 Planhat companies." An answer means you are done.

Switching from a manual install? Remove the old planhat entry from claude_desktop_config.json first, or you'll see two copies of every tool.

Manual install (Cursor and other MCP clients)

For MCP clients other than Claude Desktop, or if you prefer running from a checkout. Requires Node.js 18 or newer.

1. Get the code and build the server:

git clone https://github.com/da-troll/planhat-mcp.git ~/planhat-mcp
cd ~/planhat-mcp
npm install
npm run build

2. Add your Planhat token:

cp .env.example .env
open .env        # paste your token after PLANHAT_TOKEN= and save

The token stays in that one file on your machine. Treat it like a password.

3. Register the server in your client's MCP config (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json), replacing YOUR-USERNAME:

{
  "mcpServers": {
    "planhat": {
      "command": "node",
      "args": ["/Users/YOUR-USERNAME/planhat-mcp/dist/server.js"]
    }
  }
}

Restart the client and test with the same question as above.

What Claude can do with it

60 tools across 12 Planhat resource types. Every resource supports the same five verbs: list, get, create, update, delete.

Resource	What it is
Companies	Your customer accounts
Contacts (end users)	People at those customers
Opportunities	Sales/expansion deals
Notes	Logged notes on an account
Conversations	All logged touchpoints: emails, calls, notes, tickets
Users	Your own team members in Planhat
Assets	Products/objects tied to a customer
Issues	Bugs and feature requests
Tickets	Support tickets
Tasks	To-dos and scheduled activities
Licenses	Recurring revenue records
Invoices	Billing records

Claude only ever does what you ask, and the token you create controls what it can touch. A read-only token makes the whole connector read-only.

Optional hardening

Two switches cap what any connected AI can ever do, no matter what it's asked. Bundle installs get them as checkboxes in the install pop-up; manual installs add either to the .env file:

Setting	Effect
PLANHAT_READ_ONLY=1	Only the list/get tools exist; nothing in Planhat can be changed.
PLANHAT_DISABLE_DELETE=1	Everything works except deleting records.

Every tool also carries the standard MCP annotations (readOnlyHint, destructiveHint), so clients that calibrate their permission prompts per tool (asking before destructive calls, auto-approving reads) get the right signals. Whether and when to prompt is always the client's decision; the switches above and the permissions on the Planhat token itself (see SECURITY.md) are the hard limits.

The shipped bundle contains just four files: manifest.json, dist/server.js (one dependency-free build), LICENSE and README.md.

Troubleshooting

Symptom	Likely cause & fix
Double-clicking the .mcpb does nothing, or Install is greyed out	Update to a recent Claude Desktop; older builds predate one-click .mcpb extensions. You can also install from Settings > Extensions > Advanced > Install Extension.
Every Planhat tool appears twice	The bundle and an old manual config entry are both installed. Remove mcpServers.planhat from claude_desktop_config.json.
Claude says it has no Planhat tools	Claude Desktop only reads its config on launch. Quit it fully, reopen, and check the JSON has no trailing commas.
HTTP 401 Unauthorized in a tool result	The token is wrong, expired, or was rotated. Paste a fresh one.
PLANHAT_TOKEN is not set	Bundle installs: re-open the extension's settings and fill in the token. Manual installs: there is no .env beside the server, so repeat manual step 2.
command not found: node (manual install)	Install Node.js 18 or newer, or point command at the full path to your node binary.
Tool works but returns []	Usually not an error: that Planhat resource is genuinely empty for your filters.

For engineers

npm install          # install dependencies
npm test             # offline test suite (never touches the live API)
npm run typecheck    # TypeScript type checking
npm run build        # produce dist/server.js
npm start            # run the built server over stdio

Build the one-click bundle locally with npm run build && npx -y @anthropic-ai/mcpb@2.1.2 pack . planhat.mcpb.

Architecture notes, API quirks, and contribution rules live in AGENTS.md and CONTRIBUTING.md. Endpoint paths were verified against the live Planhat API in July 2026. Notably, Planhat has no /notes or /activities REST endpoints; notes and tickets are /conversations under the hood (see AGENTS.md for the full story).
