Overview

AI-generated overview

Lets an assistant check Nigerian business names, CAC fees and the public register, and manage FastCAC business registrations, payments and documents.

What you can do
  • Search CAC's public register by name or RC/BN number and read Tax IDs
  • Check name availability and compliance, generate checked name ideas, and find exact CAC line-of-business entries
  • Calculate CAC registration fees and annual returns due
  • Create, rename, list and delete draft registrations, and read registration state, documents and CAC status
  • Handle payments, credits, subscriptions, discount codes, WhatsApp verification and NIN steps through action links
  • Manage share links, notifications and notification preferences
When to use it
Useful when someone is registering or researching a Nigerian business with the CAC: checking whether a name will pass, what government fees apply, whether a company already exists, or tracking an in-progress FastCAC registration and its payments.
Requirements
Remote streamable HTTP endpoint; no local install. The CAC lookup tools are free and need no account. Tools for the user's own businesses require signing in to FastCAC, and personal registrations require a verified WhatsApp number. Payments are in naira.
Before you install
Tools can create, rename and delete draft registrations, revoke share links and mark notifications read. Payments, credit purchases and subscriptions go through Paystack and spend money. NIN and identity details are entered by the user in a secure field, not in chat. A tool error does not mean a name is free or that no register match exists.

Installation

In SourceWeft

  1. Open FastCAC in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.fastcac%2Fcac/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

calculate_cac_fees

Calculate CAC registration fees

CAC's official registration fees, line by line, for a business name, a limited company (by authorised share capital, default ₦1,000,000) or an NGO (Incorporated Trustees). Use it for any question about what CAC charges to register. These are government fees, not FastCAC's price.

Parametersentityrequiredshare_capital

check_annual_returns

Work out annual returns due

For a CAC business name: which annual returns are due from its registration date, which are overdue, CAC's estimated charge, and when the next one is due. Needs the registration date (it's on the certificate). Without it, the annual returns checker on fastcac.com looks the date up by BN number.

Parametersregistration_daterequired

check_business_name_compliance

Run CAC's name compliance check

Run a proposed business name and its exact CAC line of business through CAC's own compliance and similarity checker. Returns compliance/similarity scores and, when the name is too close to an existing one, CAC's suggested alternatives. Slower and rate limited: use it for a name the user is seriously considering.

Parametersproposed_namerequiredline_of_businessrequired

check_name_availability

Check a name against CAC's register

Search CAC's public registry for names matching or similar to a name, across every registration type (business names, companies, LLPs, trustees). CAC rejects a new name that's too close to any of them, active or inactive. close_matches share a distinctive word with the name: any close match means the name is at risk. other_matches only share generic words. An empty close_matches usually means it's available, but CAC makes the final call.

Parametersnamerequired

generate_business_names

Suggest business names

Brainstorm CAC-registrable business names for an idea. Each name comes back already checked against CAC's registry, with `availability`: likely_available, similar_names_exist, or unchecked (CAC's search was busy).

Parametersidearequiredline_of_business

get_cac_tax_id

Get a registered business's Tax ID

Get the Tax ID (TIN) CAC's public search shows for a registered business. Takes company_id, rc_number and classification_id from a search_cac_register result. Returns { name, rc_number, tax_id }, or an error 'not_found' when CAC has none.

Parametersrc_numberrequiredcompany_idrequiredclassification_idrequired

get_nin_request_status

Check a NIN request

Where a request from start_nin_request stands: status (waiting_for_person, started, settling, verified, failed, expired, paid, delivered, delivery_failed), next_step in words, the products and their naira prices. Never the NIN or the person's details: those go only to the person.

Parametersrequest_handlerequired

search_cac_register

Search CAC's public register

Search the Corporate Affairs Commission's (CAC) public register for businesses already registered in Nigeria, by name or by RC/BN number. Returns `results`: name, rc_number (the BN number for a business name), registration_date, classification, nature_of_business, status (e.g. ACTIVE or INACTIVE), company_id, classification_id and match (exact, close, similar or null), best match first. This lists what exists; it isn't an availability check (check_name_availability and check_business_name_compliance are). An `error` never means there's no match.

Parametersqueryrequiredentity_type

search_line_of_business

Find a CAC line of business

Find exact entries in CAC's line-of-business picklist matching what the business does.

Parametersqueryrequired

start_nin_request

Start a NIN or NIN slip request

Start a paid request on fastcac.com for: 'slip' = the person's NIMC NIN slip (PDF and print-ready image), using their NIN; 'phone' = the person's NIN, found with the phone number they registered with NIMC (on fastcac.com they can add the slip; you can't request it here). Returns a link for the person and a request_handle for you. The person does a live face check and pays on fastcac.com (₦1,000 for the slip; ₦500 for the NIN, ₦1,200 with the slip); the result goes only to them. Starting is free and charges nothing.

Parameterskindrequired

apply_discount_code

Apply a discount code

Apply a discount code the user gives you to a registration that isn't paid yet.

Parameterscoderequiredbusiness_idrequired

create_business

Start a business registration

Start a new registration: creates the business (as a draft) with the name the user wants to register, in the workspace they're in (pass `workspace` only when they ask for the other one). A personal registration needs a verified WhatsApp number: without one it returns whatsapp_unverified (request_whatsapp_verification sets it up).

Parametersnamerequiredworkspace

delete_business

Delete a business

Delete one of their businesses that hasn't been paid for (draft or pending_payment) with its registration details and documents. If it can be deleted, a Confirm button is shown and nothing is deleted until they tap it; if not, you get the reason (e.g. it's been paid for). Call it only when they ask to delete it - not when they just ask whether they can.

Parametersbusiness_idrequired

fetch_nin_slip

Fetch the NIN slip for a registration

Get their NIN slip for them from NIMC's record for their confirmed NIN, instead of them uploading a photo of it. Free to them. Only after they agree, and only once their NIN is confirmed. The slip is never shown to them.

Parametersbusiness_idrequired

get_action_status

Check a step on FastCAC

Whether the person finished a step you handed them on FastCAC (a tool returned status 'action_required' with an action_id): confirming a change, paying, uploading documents, entering their NIN or verifying WhatsApp. Returns status (pending, started, completed, failed, cancelled, expired) and next_step in words.

What they can do right now and why not: the workspace they're in and who they register for, the Agent subscription (status, renewal, days left), credits, WhatsApp, personal drafts, whether a registration can start in each workspace (and the tool that unblocks it), credit purchases, and features switched on for them.

It never includes personal details (NIN, date of birth, phone, addresses); those are on the registration page.
