Open Finance BR PISP — Pix payment initiation. Operator triggers a payer→payee transfer through Iniciador's PISP license; payer authorizes once at their bank's app and the payment fires from the payer's own bank account. Alternative to merchant-acquirer rails when the payer's bank should be the source of funds. API key (X-API-KEY) + OAuth2 consent for some flows. Alpha on npm — endpoint set provisional pending live-validation.

Limitations

  • The server does not start without its environment variables set, not even to list its tools.
  • The package manifest does not declare 1 of the 2 variables the code reads.
  • The package manifest declares INICIADOR_CLIENT_ID, INICIADOR_CLIENT_SECRET, which the code does not read.
  • The npm package ships no server.json manifest.
  • Hosted calls with a test key are not available: the runtime has not recorded this provider's test behaviour (test venue unclassified).

Quickstart

Install, set the credentials, make the first call.

Pick your client. The server runs locally over stdio, with your own credentials.

Add the server to your clientOne config entry. No build step, no SDK required.
Set the environment variables2 variables read by this server's code, listed below.
Restart and make the first callThe agent can call any of the 9 tools. Try list_institutions first.
terminal
# Claude Code claude mcp add iniciador -e INICIADOR_API_BASE=… -e INICIADOR_API_KEY=… -- npx -y @codespar/mcp-iniciador@0.1.2 # then: /mcp to confirm the server is connected
Environment variables2 variables
INICIADOR_API_BASEAPI base URL — defaults to Iniciador production. Override for sandbox.optional
INICIADOR_API_KEYRead by the code; the package manifest does not declare it.

Names read from the package code (@codespar/mcp-iniciador@0.1.2). Descriptions and flags come from its manifest. Self-hosted, you hold the credentials.

Tools

What your agent can call.

9 tools, as the package's tools/list returns them.

list_institutions

List Brazilian banks supported for Pix payment initiation. Iniciador endpoint: GET /institutions.

create_consent

Create a payment consent that the payer will authorize at their bank. Iniciador endpoint: POST /consents.

get_consent

Fetch a payment consent and its current authorization status. Iniciador endpoint: GET /consents/{id}.

revoke_consent

Revoke a payment consent before it is exercised. Iniciador endpoint: DELETE /consents/{id}.

create_payment

Initiate a Pix transfer once a consent has been authorized. Iniciador endpoint: POST /payments.

get_payment

Fetch a payment by id (status, E2E id, error reason if rejected). Iniciador endpoint: GET /payments/{id}.

list_payments

List payments in a date range with optional filters. Iniciador endpoint: GET /payments.

cancel_payment

Attempt to cancel a payment that has not yet settled. Iniciador endpoint: POST /payments/{id}/cancel.

get_authorization_url

Build the URL where the payer authorizes a consent at their bank. This is a helper — it does not call Iniciador. Returns the standard OFB authorization URL using the consent id + redirect URI.

Names and descriptions come from the package's tools/list (@codespar/mcp-iniciador@0.1.2). A kind (read, write, delete) is shown only when the package annotates its tools or each tool was verified one by one; neither exists for this server yet.

Compatibility

MCP is a protocol. Any client that speaks it can mount this server.

codespar_discover lists this server's tools, but a project with a test key cannot call them yet: the runtime has not recorded what this provider does in test mode, and refuses rather than guess.

Questions

Before you install.

How do I install the Iniciador MCP server?

Run npx -y @codespar/mcp-iniciador@0.1.2 and add the config block above to your MCP client: Claude Code, Cursor, Claude Desktop, VS Code, or any MCP-compatible client. No build step, no SDK required.

What can my agent do with Iniciador?

Iniciador exposes 9 tools for payments. Your agent calls them directly; the full list is above.

How does Iniciador authenticate, and how are credentials stored?

Iniciador uses API Key. Self-hosted, you hold the credentials: the server reads them from its environment variables.

How does Iniciador handle upstream API changes?

Every server is versioned independently on npm. The command on this page pins 0.1.2, the version whose tools are listed here; your agent keeps running it until you change the version.

Is Iniciador open source? How do I report a bug?

Yes. Iniciador is MIT-licensed and published on npm as @codespar/mcp-iniciador, source on GitHub (link in the Details panel). Report issues on the package repository; security issues go to security@codespar.dev, and we respond within 24 hours.

Start in seconds.

Add the config above, set the variables, and your agent calls the tools.
