Gryzzly - Prisme.ai

The Gryzzly app provides read/write access to the Gryzzly time-tracking SaaS through its v1 REST-RPC API. It can be used either as a Builder app (automations call Gryzzly instructions directly) or as a remote MCP server consumed by an Knowledges agent — covering customers, projects, tasks, declarations (time entries), leave periods, discounts, purchases, users, groups and tags.

Time Tracking

Declarations, leave periods and exports for payroll and invoicing

Project Structure

Customers, projects, tasks and metrics with budgets and contributors

Admin & Org

Users, roles, groups, groupsets, tags and tagsets

Prerequisites

A Gryzzly account with administrator access
An API key generated in Dashboard > Administration > API Keys
Base URL (default: https://api.gryzzly.io/v1)

Usage as App
Usage as MCP

Installation

Go to Apps in your workspace
Search for Gryzzly and install it
Open the app instance configuration and fill in the required fields

Configuration

Field	Description
Gryzzly API Base URL	Base URL of the Gryzzly API (default `https://api.gryzzly.io/v1`)
API Key	Gryzzly API key, stored as a workspace secret. Passed as `Authorization: Bearer <token>`
MCP Endpoint	Auto-populated on install — URL of the MCP endpoint for this instance
MCP API Key	Auto-populated on install — signed key used in the `mcp-api-key` header. Do not modify

MCP Endpoint and MCP API Key are generated automatically by the onInstall flow and are only needed to expose this instance as an MCP server (see the next tab).

The Gryzzly app ships with a built-in MCP server. Each app instance gets its own signed mcp-api-key that encodes the workspace ID and a credentials lookup URL — the Gryzzly API key itself is never passed through headers and is resolved server-side from the app configuration.

Plug into an Agent Creator capability

Agents consume MCP servers directly through Agent Creator capabilities. This is the preferred way to expose Gryzzly to an agent.

Create or open a workspace

From the Prisme.ai console, create a new workspace (or open the one that will host the connector).

Install the Gryzzly app

Open the workspace Imports panel, search for Gryzzly and install it.

Configure the credentials

Open the freshly installed app instance settings and fill in the required fields (see the Usage as App tab for the field-by-field reference).

Copy the MCP endpoint and API key

Still on the app instance configuration page, copy the values of MCP Endpoint and MCP API Key — both are generated automatically on install.

Open Agent Creator

Switch to Agent Creator and open the agent you want to extend.

Add a capability

Add a new capability to the agent:

If a dedicated Gryzzly capability exists — select it and paste the MCP API Key into the mcp-api-key field. The server URL is already wired.
Otherwise — select the generic custom_mcp capability, paste the MCP Endpoint into the Server URL field, then open the Headers field and add an mcp-api-key entry whose value is the MCP API Key copied earlier:
```
{
  "mcp-api-key": "your-mcp-api-key"
}
```

Save

The agent now has access to every Gryzzly tool exposed by the MCP server.

Brief the agent in its system prompt

Wiring the capability is not enough — the agent also needs to know the MCP exists and when to reach for it. Add a short paragraph to the agent’s system prompt. Copy-pasteable starter:

You have access to the Gryzzly MCP server. Use it whenever the user asks about time-tracking data — customers, projects, tasks, declarations, leave periods or payroll exports. Examples: "How many hours did I declare last week?", "Create a new project under customer Acme", "List my pending leave requests", "Export this month's declarations as CSV". Prefer calling MCP tools directly over guessing, and confirm with the user before any destructive action (delete a project, remove a declaration, cancel a leave period).

Refine the trigger keywords (customer names, project codes, internal task labels) so the agent reliably picks up the right intent in your context.

Legacy MCP Install (Advanced > Tools)

Use this flow to plug the Gryzzly MCP into an Knowledges agent that does not yet support the native MCP picker.

Install the Gryzzly app

Install and configure the app in the same workspace as your agent (see the Usage as App tab). Once configured, mcpEndpoint and mcpApiKey are auto-populated.

Copy the MCP credentials

Open the app instance config and copy the values of MCP Endpoint and MCP API Key.

Open your Knowledges project

Navigate to Advanced > Tools.

Add an MCP tool

Click Add and select the MCP tab.

Fill in the endpoint

Paste the MCP Endpoint URL copied from the app instance.

Add the auth header

In the Headers field, add the signed API key:

{
  "mcp-api-key": "your-mcp-api-key"
}

Save

The agent can now list and call Gryzzly tools through the MCP endpoint.

The signed mcp-api-key encodes the workspace ID and the getConfig webhook URL. The MCP server validates the signature using the central app secret and transparently fetches the Gryzzly API key and base URL from the installed app. Credentials are cached per tenant for 10 minutes.

Output Formats

Every tool accepts an outputFormat parameter that controls the MCP response shape:

verbose (default) — human-readable text for LLM consumption
structured — machine-readable JSON in structuredContent
both — both text and structured content

Error Handling

HTTP Status	Error	Solution
401	Unauthorized	Verify the API key and `baseUrl`
403	Forbidden	Check the Gryzzly role of the API key owner
404	Not Found	Verify UUIDs for project, task, user, etc.
422	Validation	Check required fields and enum values (roles, visibility, budget type, etc.)
429	Rate Limited	Back off and retry with exponential delay

Common Issues

“Not configured” — The app instance has no API key. Generate one in Gryzzly > Administration > API Keys and paste it in the app configuration. “Invalid API key” (MCP) — The mcp-api-key header does not match the central app secret. Reinstall the app instance to regenerate a signed key. “Credentials lookup failed” — The MCP endpoint could not reach the getConfig webhook of the installed app. Verify that the app instance is still installed in the expected workspace. contributors rejected on public project — Set visibility: private or leave contributors empty.
