## MCP tools (4)

### `validate_postcode` (~70 tokens)

Validate a Nigerian postcode

Check a postcode's structure offline and return its canonical forms and segments.

Free and instant. Does not confirm the code is assigned to a building; use
lookup_postcode for that.

Input parameters:

- `postcode` (string, required): Code in any style, e.g. 'ek 01 a03 fk 01'.

Output parameters:

- `compact`: Compact form for storage, e.g. EK01A03FK01.
- `error`: Why the code is malformed.
- `postcode`: Canonical form, e.g. EK-01-A03-FK-01.
- `segments`
- `spaced`: Form shown to people, e.g. EK 01 A03 FK 01.
- `suggestion`: A well-formed code if look-alike characters (O/0, I/1, S/5, B/8) were the only problem. Confirm it with the user before using it.
- `valid` (boolean): Whether the code is well formed. It may still be unassigned.

### `lookup_postcode` (~75 tokens)

Look up a Nigerian postcode

Confirm a postcode is assigned to a building. Free.

For the address and building details, use lookup_postcode_details.

Input parameters:

- `level` (integer): Always 1. Higher levels are lookup_postcode_details.

Output parameters:

- `administrative_address`: Level 2 and up.
- `building_use_status`: Level 3 and up, e.g. residential.
- `note`: Why the answer may be incomplete, such as a test key.
- `other_building_info`: Level 4 and up, unstructured.
- `point_geometry`: Level 5, unstructured.
- `postcode` (string)
- `recent_house_address`: Level 2 and up. Personal data.
- `status`: valid, not_found, or invalid for a malformed code.
- `valid` (boolean): Whether the code is assigned to a building.
- `verified`

### `autocomplete_postcode` (~43 tokens)

Autocomplete a Nigerian postcode

Suggest completions for the next segment of a partly typed postcode.

Input parameters:

- `partial` (string, required): The start of a code, e.g. 'EK 01 A'.

Output parameters:

- `segment`: The segment being completed.
- `suggestions` (array)

### `find_postcode_at_location` (~99 tokens)

Find the postcode at a location

Return the postcode of the nearest building to a coordinate in Nigeria.

Names and the house address are withheld unless NG_POSTCODE_MAX_LEVEL is 2 or more.

Input parameters:

- `latitude` (number, required): Latitude in decimal degrees, e.g. 7.6211.
- `longitude` (number, required): Longitude in decimal degrees, e.g. 5.2214.
- `max_distance_m`: Search radius in metres. Defaults to 25.

Output parameters:

- `area`: Enclosing area code, e.g. EK-01-A03-FK.
- `depth`: How deep the match goes, e.g. unit.
- `district`
- `found` (boolean): False when no building is within the radius.

Nigeria Postcode is an MCP server listed in the public MCP registry as io.github.Adeniyikayodee/ng-postcode. Validate, look up and resolve addresses to Nigeria's NIPOST digital postcodes (NDAPS). This page covers its npm package (ng-postcode-mcp).

### Is the Nigeria Postcode MCP server safe to use?

Nigeria Postcode scores 87 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 16 October 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. 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 Nigeria Postcode MCP server expose?

Nigeria Postcode exposes 4 tools: validate_postcode, lookup_postcode, autocomplete_postcode, find_postcode_at_location. Their descriptions and schemas cost roughly 287 tokens of context every time the server is loaded.

### Is the Nigeria Postcode MCP server still maintained?

Nigeria Postcode is still listed as active in the MCP registry. We last reached this channel on 16 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Nigeria Postcode MCP server under?

Nigeria Postcode declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
