Schema Quality & AI Usability77
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1778 tokens (~197/item across 9 items; 8 tools + 1 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management73
- Stability observed for 22 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

extend_session Extend a parking session ~267
Prices more time on an active hourly parking session. No API key needed. Requires phone_code (the 6-character code on the driver's receipt or pass), plate_last3 (the last 3 characters of the plate) and extend_hours (0.5 to 8, in half-hour steps); session_id with session_code works in place of the two codes. Returns the price, the new end time once paid and a pay_url to the driver's session page, where the driver pays. Nothing is charged and the end time doesn't move until the driver pays there. Any mismatch returns the same answer, SESSION_NOT_FOUND. Every payment completes on parkgraph.com with the driver present; no tool charges money on its own.

The signed-in driver's own parking: recent sessions (newest first), spaces held through this connector, and monthly passes, each with a link to its page on parkgraph.com. Requires driver sign-in to Park Graph through this connector; without sign-in the call answers 401 with the sign-in details. Sessions are matched by the driver's verified sign-in email (the email on their receipts). get_session checks one session without sign-in, by phone code. Every payment completes on parkgraph.com with the driver present; no tool charges money on its own.
| Name | Type | Req | Description |
|---|---|---|---|
| active_only | boolean | – | Only sessions that are parked now and holds that haven't expired |
No output schema declared.
No examples provided.
my_vehicles My vehicles ~185
The signed-in driver's saved vehicles (up to 5 plates, each with an optional label) and plates from their past parking that aren't saved yet. action list (the default) only reads; save adds a plate or sets its label, rename changes a label, remove deletes a saved plate. Saving or removing the same plate twice changes nothing. A saved plate works as reserve's plate. Requires driver sign-in to Park Graph through this connector; without sign-in the call answers 401 with the sign-in details. Every payment completes on parkgraph.com with the driver present; no tool charges money on its own.
| Name | Type | Req | Description |
|---|---|---|---|
| action | string | – | What to do |
| label | string | – | A name for the vehicle, for save and rename ("Work truck") |
| plate | string | – | The plate, for save, rename and remove (spaces and dashes are ignored) |

quote Quote a price ~129
Price to park at a lot for a number of hours, at the lot's current rate (daily max applied). No API key needed. booking.mode in the result is the next step: reserve (the reserve tool holds a space) or pay_at_qr_page (booking.pay_url is the lot's pay page, where the driver pays and parks). Every payment completes on parkgraph.com with the driver present; no tool charges money on its own.
| Name | Type | Req | Description |
|---|---|---|---|
| duration_hours | number | yes | How long the driver will park, in hours |
| lot_id | string | yes | Lot id from search_lots |
No output schema declared.
No examples provided.
reserve Reserve a space ~294
Holds space at a lot for the driver for a few minutes and returns booking_url, the lot's pay page on parkgraph.com (opened on duration_hours when it is sent). No API key needed. A hold takes a real space until it expires or the driver pays. Lots that take payment at their QR page place no hold: the result is status pay_at_qr_page with a pay_url, the lot's pay page. Every payment completes on parkgraph.com with the driver present; no tool charges money on its own.
| Name | Type | Req | Description |
|---|---|---|---|
| agent_platform | string | – | The calling assistant's platform (recorded on the booking) |
| duration_hours | integer | – | Hours to book. The result's booking_url opens the lot's pay page on this length |
| end | string | – | Departure time (ISO 8601) |
| idempotency_key | string | – | A repeated key retries safely. Generated when omitted and returned in the result. |
| intent | string | – | What the driver needs, in plain words (optional) |
| lot_id | string | yes | Lot id from search_lots |

Every payment completes on parkgraph.com with the driver present; no tool charges money on its own.
| Name | Type | Req | Description |
|---|---|---|---|
| lat | number | yes | Latitude of the driver's destination |
| limit | integer | – | Maximum number of lots returned |
| lng | number | yes | Longitude of the driver's destination |

How do I install the Park Graph MCP server?
Park Graph is a hosted endpoint at https://parkgraph.com/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the Park Graph MCP server?
Park Graph is an MCP server listed in the public MCP registry as com.parkgraph/mcp. Find, price and book parking at Park Graph lots: search, quote, hold and session tools. This page covers its hosted endpoint (https://parkgraph.com/api/mcp).
Is the Park Graph MCP server safe to use?
Park Graph scores 77 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Park Graph MCP server expose?
Park Graph exposes 8 tools: search_lots, get_lot, quote, reserve, get_session, and 3 more. Their descriptions and schemas cost roughly 1,439 tokens of context every time the server is loaded.
Does the Park Graph MCP server require authentication?
No. We connected to Park Graph without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Park Graph MCP server still maintained?
Park Graph is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What did VerifyMCP test on the Park Graph MCP server?
VerifyMCP ran 13 checks on Park Graph, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
