com.agishub/agent-memory (MCP Server)

This MCP server provides persistent semantic memory for AI agents. It stores and recalls text based on meaning, supporting retrieval workflows such as RAG and vectorization. The server’s described purpose is “Persistent semantic memory for AI agents: store and recall text by meaning (RAG, Vectorize).”

🛠️ Key Features

Persistent semantic memory for AI agents
Store and recall text by meaning
Supports RAG and vectorization (“Vectorize”)

🚀 Use Cases

Retrieval-augmented generation (RAG) workflows
Systems that need semantic recall rather than keyword matching

⚡ Developer Benefits

Meaning-based text retrieval for agent systems
A memory layer aligned with RAG and vector-based approaches

⚠️ Limitations

Limited information available: no details provided on interfaces, tools, storage backend, or configuration options beyond the description and “x402” marker.

AgisHub

Pay-per-call tools for AI agents — no signup, no API keys, just USDC.

Live data & utilities over x402 micropayments on Base. Your agent pays a few tenths of a cent per call from its own wallet; no accounts, no monthly plans.

Why AgisHub

Traditional APIs make an agent stop and ask a human: sign up, create an account, copy an API key, add a credit card, read the docs. AgisHub tools are callable the moment an agent has a funded wallet — the server answers HTTP 402, the agent signs a USDC payment on Base, and the data flows back. Under a second, no human in the loop.

Two doors, one platform

MCP (free) — remote Model Context Protocol server. Point Claude / Cursor / any MCP client at the URL and the tools appear.
HTTP x402 (paid) — POST /v1/<tool>; unpaid requests get a 402 challenge, the client signs a USDC payment (EIP‑3009 on Base) and retries. USDC contract 0x8335…2913.

HTTP (paid):  POST https://api.agishub.com/v1/<tool>

Tools

Prices are per call in USDC on Base. Tools on both channels are free via MCP and priced via HTTP x402.

🕔 timezone — world clock, date math & scheduling for agents

Tool	What it does	Channels	Cost (x402)
`now_in`	Current local time in an IANA timezone — UTC offset, abbreviation, DST flag.	MCP · HTTP	$0.001
`convert_timezone`	Convert a datetime between two IANA zones. Accepts ISO 8601 or natural language ("next Tuesday 3pm").	MCP · HTTP	$0.001
`convert_batch`	Convert one instant into many zones at once — ideal for world‑clock views.	MCP · HTTP	$0.001
`tz_offset`	Exact UTC offset of a zone at a given instant (DST‑aware; handles +05:30, +05:45).	MCP · HTTP	$0.001
`lookup_timezone`	Resolve a city or country to its IANA timezone(s). "Delhi" → `Asia/Kolkata`.	MCP · HTTP	$0.001
`date_math`	Add/subtract time respecting DST, or diff two datetimes across zones.	MCP · HTTP	$0.001
`find_meeting_slots`	Overlapping working‑hour slots across timezones (skips weekends & public holidays).	MCP · HTTP	free: 1 slot · $0.02: all
`is_holiday`	Is a date a public holiday in a country (ISO 3166‑1)? Data from Nager.Date.	MCP · HTTP	$0.001
`list_timezones`	List or search valid IANA timezone names.	MCP	free

🕸️ Agis Web Scraper — read any web page as clean markdown

Tool	What it does	Channels	Cost (x402)
`extract`	Fetch any public URL and return its main content as clean markdown (title, headings, links, lists). Optional `render:true` runs a headless browser for JS‑heavy pages / SPAs. Built for RAG and agents that need to read the web.	HTTP	$0.004

More tools land here as the platform grows — each new service plugs into the same MCP + x402 doors.

Quick start

Use the free MCP tools (Claude Code example):

bash

claude mcp add --transport http timezone https://api.agishub.com/mcp

Pay per call over HTTP x402 (any x402 client / wallet):

bash

# Unpaid → 402 challenge; an x402-aware client signs & retries automatically.
curl -X POST https://api.agishub.com/v1/web-scraper \
  -H 'content-type: application/json' \
  -d '{"url":"https://example.com","render":true}'

Your agent's wallet only needs USDC on Base — the facilitator covers gas.

For agents & LLMs

Payments are real USDC on Base mainnet and irreversible. Fund a dedicated agent wallet with a small balance; that balance is your spending cap.
The free MCP tier never charges. Only the /v1/* (x402 HTTP) routes take payment.
extract fetches arbitrary public URLs; it will not reach private/internal hosts.

Pricing

Per‑call, in USDC on Base — no subscription. Roughly: $1 ≈ 1,000 timezone calls, ≈ 250 web extractions, or 50 full meeting‑slot searches. Settlement fees on Base are a fraction of a cent and paid by the facilitator.

namespace	string	required	Your collection key — groups and isolates your memories. Treat it like a secret: anyone with it can read/write this collection.
text	string	required	The text/content to store and make searchable.
id	string	optional	Optional stable id to update an existing entry; auto-generated if omitted.

namespace	string	required	The namespace to search within (the same key used on upsert).
query	string	required	Natural-language query; returns the most semantically similar stored entries.
top_k	integer	optional	How many results to return (default 5).
