Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account michaelyousrie for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Lets an assistant list, inspect, and run saved HTTP requests from MailPal collections, and on Pro create new requests.

What you can do: MailPal is an HTTP/API client for VS Code whose bundled MCP server also ships standalone on npm. Through it an assistant can list and inspect saved requests in MailPal collections and run them, with write tools such as creating requests reserved for Pro. It reads collections from a workspace folder and records run history locally.
When to use it: Useful when you already keep API requests in MailPal collections and want an assistant to review or execute them during development or debugging, instead of rebuilding calls by hand. Less relevant if you do not use MailPal or keep requests elsewhere.
Requirements: Runs as a local stdio process, typically started with npx, so Node.js and network access to npm are needed. It reads collections from the folder given by MAILPAL_WORKSPACE and writes run history to MAILPAL_HISTORY_DIR (default ~/.mailpal/history). Desktop only; no authentication is declared. Pro is needed for write tools.

Before you install

Running saved requests sends real HTTP traffic to whatever endpoints those requests target, which may change or delete remote data. Requests may carry credentials or secrets; per-collection secret values are described as stored in the OS keychain rather than in files. Run history is written to MAILPAL_HISTORY_DIR on disk, so review what that directory retains.

Installation

In SourceWeft

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

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

MailPal

The honest API client for VS Code.
Collections, variables, unlimited history, an MCP server for AI agents, and a free tier that stays free.

Install from the VS Code Marketplace

[MailPal request panel]

Why MailPal exists

The most popular REST client for VS Code has 7.4 million installs and a 2.5 star rating, because its free tier slowly moved everything, including your own request history, behind a paywall.

MailPal makes the opposite promise, and treats it like a contract:

The free tier is fully usable for a single user, forever.
Unlimited requests, unlimited collections, unlimited local history.
Pro adds new value only. It never gates access to your own data.
If a license lapses, Pro features stop. Everything else keeps working.

Highlights

Full request builder with a Postman-style editor: auto-growing key/value rows, header autocomplete, color-coded JSON editing with format and validation
Auto headers surfaced, so you see and control everything sent on the wire
Syntax-highlighted responses (JSON and XML), HTML raw/preview toggle, resizable request/response split
Per-collection variables with {{VAR}} placeholders; secret values live in your OS keychain, never in files
Unlimited local history with one-click re-send
Import Postman v2.1, Thunder Client, OpenAPI 3.x, and curl; export Postman and curl
Assertions per request with pass/fail on every send
A bundled MCP server, registered with VS Code agent mode automatically, so AI agents can list, run, and (with Pro) create requests

For AI agents (MCP)

The MCP server also ships standalone on npm as mailpal-mcp:

Works with any MCP client (Cursor, Claude Desktop, and friends) via npx -y mailpal-mcp.
