PyGen toolset

The PyGen toolset provides read-only access to SnapLogic's Snap knowledge base for text-to-pipeline generation. Use these tools from an MCP client to look up available Snaps, query usage examples, retrieve Snap parameters and documentation, and validate pipeline designs before building them.

All PyGen toolset endpoints share the base path /api/1/rest/public/platform_mcp/mcp/pygen.

Note: The PyGen toolset is available only when PyGen is configured for the environment. If /mcp/pygen returns 404 or /mcp exposes only 12 tools, PyGen is not wired for that environment.


PyGen toolset APIs
`POST /platform_mcp/mcp/pygen`	sends a JSON-RPC 2.0 request to the Platform MCP Server using the PyGen toolset and returns the response as a Server-Sent Events (SSE) stream.
`GET /platform_mcp/mcp/pygen`	opens a persistent Server-Sent Events (SSE) stream for receiving server-initiated messages from the Platform MCP Server on the PyGen toolset.
`DELETE /platform_mcp/mcp/pygen`	terminates an active PyGen toolset MCP session and releases any associated server-side resources.

Available tools

After initializing a session, call tools/list to retrieve the live set of tools. The following 9 tools are available in the PyGen toolset:


Tool name	Description	Inputs
`pygen_get_all_snap_names`	Return a list of all Snap names available in the SnapLogic catalog.	None.
`pygen_list_snaps_by_category`	Return Snap names filtered by a given category (for example, `Transform`, `Parse`, `Write`).	`category` — Required. Snap category name.
`pygen_query_snap_examples`	Retrieve example usages for one or more Snaps.	`snap_names` — Required. List of Snap names.
`pygen_query_pipeline_examples`	Retrieve example pipelines that match a natural-language description.	`query` — Required. Description of the pipeline type or use case.
`pygen_validate_snap_names`	Validate that a list of Snap names exists in the catalog. Returns any unknown names.	`snap_names` — Required. List of Snap names to validate.
`pygen_get_snap_parameters`	Retrieve the configurable parameter schema for one or more Snaps.	`snap_names` — Required. List of Snap names.
`pygen_get_snap_documentation`	Retrieve the documentation text for one or more Snaps, including description and field-level help.	`snap_names` — Required. List of Snap names.
`pygen_get_snap_io_info`	Retrieve the input and output schema for one or more Snaps.	`snap_names` — Required. List of Snap names.
`pygen_validate_connections`	Validate that the connections between a sequence of Snaps are compatible (matching output schema to input schema).	`snap_connections` — Required. Ordered list of Snap names representing the connection sequence.

Note: PyGen tool calls are not audit-logged. These tools perform read-only queries against the Snap knowledge base and do not modify any platform resources.
