mempool-cli

mempool

A command line for Mempool.space Bitcoin data.

mempool is a single pure-Go binary. It reads public mempool data over plain HTTPS, shapes it into clean records, and prints output that pipes into the rest of your tools. No API key, nothing to run alongside it.

The same package is also a resource-URI driver, so a host program like ant can address mempool as mempool:// URIs.

Install

go install github.com/tamnd/mempool-cli/cmd/mempool@latest

Or grab a prebuilt binary from the releases, or run the container image:

docker run --rm ghcr.io/tamnd/mempool:latest --help

Usage

mempool page <path>                      # fetch one page as a record
mempool page <path> -o json              # as JSON, ready for jq
mempool page <path> --template '{{.Body}}'  # just the readable body text
mempool links <path>                     # the pages it links to, one per line
mempool --help                           # the whole command tree

Every command shares one output contract: -o table|markdown|json|jsonl|csv|tsv|url|raw, --fields to pick columns, --template for a custom line, and -n to limit. The default adapts to where output goes (a color-aware table on a terminal, JSONL in a pipe), so the same command reads well by hand and parses cleanly downstream.

This is a fresh scaffold. It ships one example resource type, page, wired end to end. Model the real mempool records in mempool/ and declare their operations in mempool/domain.go; each one becomes a command, an HTTP route, and an MCP tool at once.

Serve it

The same operations are available over HTTP and as an MCP tool set for agents, with no extra code:

mempool serve --addr :7777    # GET /v1/page/<path>  returns NDJSON
mempool mcp                   # speak MCP over stdio

Use it as a resource-URI driver

mempool registers a mempool domain the way a program registers a database driver with database/sql. A host enables it with one blank import:

import _ "github.com/tamnd/mempool-cli/mempool"

Then ant (or any program that links the package) dereferences mempool:// URIs without knowing anything about mempool:

ant get mempool://page/<path>   # fetch the record
ant cat mempool://page/<path>   # just the body text
ant ls  mempool://page/<path>   # the pages it links to, each addressable
ant url mempool://page/<path>   # the live https URL

Development

cmd/mempool/   thin main: hands cli.NewApp to kit.Run
cli/                 assembles the kit App from the mempool domain
mempool/                the library: HTTP client, data models, and domain.go (the driver)

Releasing

Push a version tag and GitHub Actions runs GoReleaser, which builds the archives, Linux packages, the multi-arch GHCR image, checksums, SBOMs, and a cosign signature:

git tag v0.1.0
git push --tags

The Homebrew and Scoop steps self-disable until their tokens exist, so the first release works with no extra secrets.
