Placekey through One
Placekey is a developer-oriented service that provides a universal identifier (Placekey) for any physical place by address or geographic coordinates, enabling easier address/POI matching, deduplication and spatial joins across datasets.
One exposes Placekey through four MCP tools. The table below carries real action ids from One's knowledge base, so for a common operation you can skip search and go straight to reading the action's parameters.
How to run an action
- Find the action in the table below, or call
search_one_platform_actions with platform placekey if it is not listed.
- Call
get_one_action_knowledge with the action id. Do this every time, including for actions in this table. The table gives you the id, not the parameters.
- Call
execute_one_action with parameters copied from that knowledge.
Never guess a parameter name, a body field, or an enum value. The knowledge has the real schema, and a guessed field is either a 400 or a silent write of the wrong thing.
Before you start
Call list_one_integrations once and confirm Placekey is connected. If it is missing, the user has not connected it: say so and point them at https://app.withone.ai rather than reaching for raw HTTP.
Each connection carries an access field. If it reports {"policy": "methods", "methods": ["GET"]} the agent is read-only here, so plan a read-only answer instead of attempting a write that will be refused.
Before a write
Creates, updates, deletes and sends land on a real Placekey account and cannot be recalled. State the action and the specific target in one line before the first write in a task, and let the user stop you. Reads need no confirmation.
Actions

| Action | Method | Path | Action id |
|---|
| Get a Placekey for a Single Query (Address, POI, or Coordinates) | POST | /v1/placekey | conn_mod_def::GJ6G_pUtyko::05nvdJsvSwexP_V76D1MtA |
Placekeys
| Action | Method | Path | Action id |

| Get Placekeys in Bulk (Batch Lookup) | POST | /v1/placekeys | conn_mod_def::GJ6G_pjDsMg::Sz31dNQeR5CLtM3XUOjslw |
When a call fails
The error comes from Placekey, not from One. A 400 or 422 means your parameters do not match the schema, so re-read the knowledge and fix the field. A 401 or 403 means the connection needs re-authorizing, which no retry will fix. A 404 means the id is not on this account. A 429 means slow down. Never retry a write more than once: the first attempt may have landed.
