FlurryPORT

Live

Tool that captures incoming webhooks exactly as received and replays them byte-for-byte to your local machine with valid signatures, for developers testing integrations, instead of waiting for a provider to refire an event.

No sign-up
What to know▼
How it works
Captures headers, body, and signature, encrypts at rest, and replays single, batch, or ordered sequences with signature verification (Simple HMAC, Svix, Stripe, Square) still passing.
What's different
Ships an MCP server so Claude Code and Cursor can capture, inspect, and replay webhooks directly.
Best for
Developers who need to repeatedly test webhook-triggered code without waiting on the real provider.

Toolport

Live

A local gateway that lets every AI coding client share one set of MCP server connections instead of configuring each tool separately, cutting how many tools your agent has to load.

FreeNo sign-upWorks offlineOpen source
What to know▼
How it works
A local-first, open-source gateway. You set up and authenticate each MCP server once, and every connected AI client — Claude, Cursor, VS Code, Codex — shares that same connection instead of you configuring it per tool.
What's different
Claims up to 91% less tool-token overhead by giving an agent a handful of meta-tools instead of loading hundreds of individual tool definitions; API keys stay in the OS keychain.
Pricing
Free, open source, no sign-up.
Best for
Developers running multiple AI coding clients against the same set of MCP servers who don't want to re-authenticate each one separately.
Watch out
The '91% overhead cut' figure is the product's own claim; we haven't independently benchmarked it.

Dynamic Feed

Live

A single API call returns live, cryptographically signed data across 87 sources so AI agents and software can verify what they're consuming — a developer-facing trust layer, not a consumer app.

No sign-upOpen source
What to know▼
How it works
A single keyless API call returns structured JSON for 87 live tools across 19 verticals; each datapoint carries its source, licence, timestamp and an Ed25519 signature, optionally Bitcoin-anchored.
What's different

Best for
Developers building AI agents or software that need to independently verify the live data they consume.

Kinet Aios

Live

A local dashboard for running Claude Code, Codex and other AI coding agents in parallel, keeping history and memory on your machine — though it still needs API access to an AI model.

No sign-up
What to know▼
How it works
A local-first dashboard for running multiple AI coding agent sessions in parallel, switching between a built-in ReAct agent, Claude Code and Codex, with support for any OpenAI-compatible or Anthropic model and any MCP server.
What's different
Keeps session history and long-term memory on your own machine in SQLite, with no account required.
Best for
Developers who juggle multiple AI coding agents and want one local dashboard instead of separate tools.
Watch out
You still need to bring your own API access to an AI model — the dashboard itself doesn't include model inference.
