## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 70/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 913 tokens (~182/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Install

### How do I install the OpenMapp MCP server?

## MCP tools (5)

### `find_gyms` (~186 tokens)

Find BJJ gyms

Find BJJ gyms near a US city, neighborhood, or ZIP. Defaults: open to drop-ins, classes today. Returns drop-in policy, visitor fee when known, matching class times, and online booking (reservePrice, reserveUrl) when the gym takes reservations.

Input parameters:

- `day` (string): Restrict to this weekday or tomorrow. Overrides today
- `drop_ins` (boolean): Only gyms marked Drop-ins (known welcome or a listed visitor/open-mat price). Default true
- `kinds` (array): Filter to Gi, No-Gi, and/or open mat
- `limit` (integer): Max gyms to return. Default 8
- `q` (string, required): City, neighborhood, address, or ZIP, same as the OpenMapp search box
- `today` (boolean): Only gyms with a listed class or open mat today. Default true

### `get_gym` (~82 tokens)

Get gym details

Full public gym card: address, drop-in policy, visitor fee, the weekly timetable, and online booking when the gym takes reservations (price and reserveUrl per class). Use an id or slug from find_gyms.

Input parameters:

- `id` (string, required): Gym id or slug from find_gyms, e.g. 10th-planet-allentown

### `start_reservation` (~215 tokens)

Start a drop-in reservation

Check that a class at a gym can be reserved online right now and get the link where the visitor signs the gym's waiver and pays (or reserves free). Returns the class's next date and start time, price, cancellation policy, and reserveUrl. It does not book anything: the visitor must open reserveUrl and sign and pay themselves. When status is unavailable, reason says why and reservableClasses lists classes that can be reserved instead.

Input parameters:

- `date` (string): YYYY-MM-DD within the next 7 days, on the class's weekday. Default: the next time the class runs
- `day` (string, required): Weekday of the class, as listed in sessions
- `id` (string, required): Gym id or slug from find_gyms or get_gym
- `name` (string): Class name from sessions. Needed only when the gym lists two classes at the same day and time
- `time` (string, required): Class start time as listed in sessions, e.g. "6:30 PM"

### `list_cities` (~106 tokens)

List covered cities

US cities OpenMapp covers, with gym counts, how many welcome class drop-ins, and how many list an open mat. Use this to check coverage before find_gyms. Filter by city name or two-letter state.

Input parameters:

- `limit` (integer): Max cities to return. Default all matching, max 500
- `q` (string): Filter by city name, e.g. Austin
- `state` (string): Two-letter US state, e.g. TX

### `map_url` (~62 tokens)

OpenMapp map link

OpenMapp map link for a city search, optionally with a gym drawer already open.

Input parameters:

- `gym_id` (string): Gym id from find_gyms to open the details drawer
- `q` (string, required): City or search text for the map search box

### Is the OpenMapp MCP server safe to use?

OpenMapp scores 84 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 OpenMapp MCP server expose?

OpenMapp exposes 5 tools: find_gyms, get_gym, start_reservation, list_cities, map_url. Their descriptions and schemas cost roughly 651 tokens of context every time the server is loaded.

### Does the OpenMapp MCP server require authentication?

No. We connected to OpenMapp without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
