Load Prophesee Metavision SDK data to DuckDB

Metavision SDK is an all-in-one toolkit for event-based vision development consisting of local Python and C++ modules rather than a web-accessible REST API. Everything needed to build a working Prophesee Metavision SDK → DuckDB pipeline is on this page: the API's base URL, authentication, endpoints, pagination and incremental field — plus a prompt that hands the whole job to your coding agent.

Build your Prophesee Metavision SDK to DuckDB pipeline

Paste this prompt into Claude, Codex, or Cursor. The agent does the rest.

PromptCopy prompt
Run uvx dlthub-init@latest to build a pipeline from Prophesee Metavision SDK to DuckDB and run it on dltHub

That scaffolds a dltHub workspace and installs the dltHub AI harness — the project rules, the secrets-management skill, and the dlt MCP server your agent needs to work safely. From there it reads the Prophesee Metavision SDK API, proposes the endpoints to load, then writes, runs and validates the pipeline while you review rather than type. Credentials are inspected through MCP tools, so your agent never reads secrets.toml itself. How the LLM-native workflow works →

Prefer to write it yourself? Every fact the agent uses is below.

Prophesee Metavision SDK API at a glance

These values come from the Prophesee Metavision SDK API reference — the authoritative source if anything here looks out of date.

---

How do I authenticate with the Prophesee Metavision SDK API?

The Metavision SDK is a local software library and does not provide a REST API for data access, thus no authentication mechanism or headers are required.

No credentials required. The Prophesee Metavision SDK API is public, so there is nothing to obtain and nothing to add to .dlt/secrets.toml — the pipeline above runs as written.

---

What Prophesee Metavision SDK data can I load into DuckDB?

These are the Prophesee Metavision SDK endpoints dlt can load into DuckDB:

---

How do I load only new Prophesee Metavision SDK records?

The Prophesee Metavision SDK API reference does not document a timestamp or sequence field for these endpoints, so there is nothing to advertise here as verified. Pick a field from the endpoints table above that increases with every write, then set it as the cursor_path.

Copy
{"name": "n_a", "endpoint": {
    "path": "n_a",
    # Replace with a field that increases on every write.
    "incremental": {"cursor_path": "REPLACE_ME", "initial_value": "2024-01-01T00:00:00Z"},
}}

On the first run dlt loads everything from initial_value; on every run after that it requests only what changed and appends with write_disposition="merge" if you set a primary key. See incremental loading.

What does the generated Prophesee Metavision SDK pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading SDK Stream Python API and SDK C++ API from the Prophesee Metavision SDK API into DuckDB:

Copy
import dlt
from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources

@dlt.source
def prophesee_metavision_sdk_source():
    config: RESTAPIConfig = {
        "client": {
            "base_url": "none",
        },
        "resources": [
            {"name": "n_a", "endpoint": {"path": "n_a"}}
        ],
    }
    yield from rest_api_resources(config)


def load_prophesee_metavision_sdk_to_duckdb() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="prophesee_metavision_sdk_pipeline",
        destination="duckdb",
        dataset_name="prophesee_metavision_sdk_data",
    )
    load_info = pipeline.run(prophesee_metavision_sdk_source())
    print(load_info)


if __name__ == "__main__":
    load_prophesee_metavision_sdk_to_duckdb()

Run it with python prophesee_metavision_sdk_pipeline.py. The agent iterates on this until it loads cleanly — you review and approve, rather than write it from scratch.

How do I query Prophesee Metavision SDK data in DuckDB?

dlt creates one table per resource. Query the loaded data with Python or SQL — or ask your agent to, through the MCP server's execute_sql_query tool.

Python (pandas DataFrame):

Copy
import dlt

data = dlt.pipeline("prophesee_metavision_sdk_pipeline").dataset()
df = data.n_a.df()
print(df.head())

SQL:

Copy
SELECT * FROM prophesee_metavision_sdk_data.n_a LIMIT 10;

See querying your data with dataset and exploring it in marimo notebooks.

---

How do I deploy the Prophesee Metavision SDK to DuckDB pipeline in production?

The pipeline runs locally, which is ideal for prototyping and one-off analysis. When you need it on a schedule, monitored on every load, and shared with your team, deploy the same dlt code on the dltHub platform — no infrastructure to maintain. The prompt above already ends with "run it on dltHub", so your agent can take it there directly.

• Deploy & schedule — run the pipeline as a managed job with automatic retries.
• Monitor — observable job queues, alerting, and load metrics for every run.
• Transform — promote raw Prophesee Metavision SDK loads into governed, documented models.
• Visualize & share — explore data in notebooks and publish live dashboards instead of static screenshots.

What other destinations can I load Prophesee Metavision SDK data to?

dlt loads into any of these — only the destination argument changes:

Set dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. On the dltHub platform the same pipeline runs against a managed Iceberg lakehouse. See the full destinations list.
