Fixpayment MCP Server

Every MCP tool requires an api_key argument. The key maps to a creditor_id and a plan (basic, reports, or full) in the mcp_api_keys table. Exposed over MCP by the fixpayment mcp mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

Its toolset

Everything the assistant can do here goes through one of these:

• ping — ✓
• get_plan_info — ✓
• get_account_summary — ✓
• list_accounts_basic — ✓
• validate_account_payload — ✓
• accounts_report — The accounts_report tool exposed by this server
• payments_report — The payments_report tool exposed by this server
• settlements_report — The settlements_report tool exposed by this server
• performance_report — The performance_report tool exposed by this server
• create_account — The create_account tool exposed by this server
• bulk_create_accounts — The bulk_create_accounts tool exposed by this server
• update_account_status — The update_account_status tool exposed by this server

Configuration

You will need 2 environment variables: FIXPAYMENT_DB_HOST, FIXPAYMENT_UPLOAD_PATH. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Adding it to your client

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

When to reach for it

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Fixpayment MCP's toolset — ping, get_plan_info, get_account_summary and 10 more — is a fair guide to whether it matches your workflow. It is maintained by prmail; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Fixpayment MCP's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Caveats

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• With 13 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Fixpayment MCP.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the fixpayment mcp mcp server does with a few real requests.
