Overview

Description from the maker (original English)

Bank statement PDF to CSV, OCR, Office to PDF, PDF to Word, any file to Markdown, merge and split.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

Common questions

Is PDF & Office Tools (Tanod) safe?

It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed today, and the latest version (0.1.8) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Tanod MCP server

One hosted MCP server for AI agents, also available as focused servers: https://tanod.dev/mcp.

  • Connection: stateless Streamable HTTP. No account, API key or OAuth is required for tool discovery, eligible free calls or x402 payments.
  • Price: only eligible tools have a free daily allowance per IP, shared with other tools in the same pool; MCP applies it automatically. Other calls require payment. Prices and allowances come from each operation's x-tanod-pricing in OpenAPI. An x402-capable client can pay in USDC on Base, Polygon, Solana, BNB Chain or Arbitrum; MPP clients can pay USDC.e on Tempo with the Tempo CLI, mppx or AgentCash. Check the quote and approve the cost before paying. See the Tanod SDKs, the x402 guide and the MPP guide.
  • Setup: https://tanod.dev/connect/. Docs for agents: https://tanod.dev/llms.txt. OpenAPI: https://tanod.dev/openapi.json.

Focused servers

Connect a focused server when you want a smaller tool list. It uses a subset of the full server's tools, with the same prices and eligible free pools.

Published guides and data

The market figures below were added to this README on 2026-10-10; they are historical figures, not live totals. Linked pages may carry their own publication or update dates.

Quick setup

Claude Code:

claude mcp add --transport http tanod https://tanod.dev/mcp

For clients that use mcpServers, such as Cursor:

{ "mcpServers": { "tanod": { "url": "https://tanod.dev/mcp" } } }

For clients that use servers, such as VS Code:

{ "servers": { "tanod": { "type": "http", "url": "https://tanod.dev/mcp" } } }

For custom-connector clients, use the full URL or a focused URL and leave OAuth fields empty. Available tools and payment support depend on the client. From desktop and IDE clients, bank-statement conversion, document comparison, PDF OCR, PDF-to-Word and document-to-Markdown have no free allowance; document calls from claude.ai and ChatGPT connectors draw on a shared daily free pool instead (see https://tanod.dev/connect/).

Other clients: https://tanod.dev/connect/.

Run locally (npx)

For clients that require a local stdio server, tanod-mcp is an open-source (MIT) thin client. Processing takes place at the hosted API, which is closed source. It forwards the hosted tool list and calls; no catalog is hard-coded. Remote-capable clients do not need this package.

Eligible free allowance applies automatically. Without a configured payment key, paid calls are not signed. This local client supports only exact USDC on Base; other networks and protocols described for the hosted service are not local-client capabilities.

Quick start
npx -y tanod-mcp

Requires Node.js 18 or newer. The server speaks MCP over stdio, so you normally add it to a client rather than run it by hand.

Claude Code
claude mcp add tanod -- npx -y tanod-mcp

With a key and caps:

claude mcp add tanod -e TANOD_PRIVATE_KEY=0x... -e TANOD_MAX_USD_PER_DAY=0.50 -- npx -y tanod-mcp
Claude Desktop

Edit claude_desktop_config.json:

{

"mcpServers": { "tanod": { "command": "npx", "args": ["-y", "tanod-mcp"] } } }

Cursor

~/.cursor/mcp.json (or .cursor/mcp.json in a project):

{

"mcpServers": { "tanod": { "command": "npx", "args": ["-y", "tanod-mcp"] } } }

VS Code

.vscode/mcp.json:

{

"servers": { "tanod": { "type": "stdio", "command": "npx", "args": ["-y", "tanod-mcp"] } } }

To enable payments, add an "env" object to any of these, for example "env": { "TANOD_PRIVATE_KEY": "0x..." }.

Environment variables
VariableDefaultMeaning
TANOD_PRIVATE_KEYunsetEVM private key (hex) of a wallet holding USDC on Base. Optional. Unset means free tier only.
TANOD_MAX_USD_PER_CALL0.05Refuse to sign any single payment above this many US dollars.
TANOD_MAX_USD_PER_DAY1.00Refuse to sign once the total for the current UTC day would pass this.
TANOD_STATE_FILE~/.tanod-mcp/spend.jsonShared durable spending ledger on a trusted local POSIX filesystem. All processes spending the same budget must use the same path. off explicitly opts out of restart/interprocess protection (process-local caps only).
TANOD_MCP_URLhttps://tanod.dev/mcpUpstream server. For testing only. Must be https://; plain http:// is accepted only for localhost, 127.0.0.0/8 or [::1]. Redirects are not followed.
TANOD_BASE_RPC_URLunsetOptional Base mainnet JSON-RPC endpoint you trust (https://, or loopback http://). Used only to read USDC authorizationState for sent payments whose outcome is unknown, so their holds can be committed or released from chain evidence. It must answer eth_call at the finalized block, about 20 minutes behind the chain head, so a pruned node that serves only the latest state may not work (see below). Redirects are not followed. Never logged.
Full-index calls

bulk_agent_index exceeds both default caps above. Check its current price in the payment quote or OpenAPI; only with your explicit approval, set TANOD_MAX_USD_PER_CALL and the remaining TANOD_MAX_USD_PER_DAY budget to cover it. Caps are never raised automatically. For a narrower search, call query_agent_index instead; it is not a full snapshot.

Code clients using @x402/mcp also enforce the core spendControls.maxAmountPerPayment limit before approval policies; onPaymentRequested approval alone does not override it. Keep wallet keys in local client configuration, never in chat.

How payment works
  1. You call a tool. The server uses its free daily allowance if it has one.
  2. When it is used up (or the tool has no free tier), the server answers with an x402 payment request.
  3. Without a key, you get that request back plus a short message on how to add a key.
  4. With a key, tanod-mcp checks the price against your two caps. If it is within both, it signs a USDC transfer authorisation (via the official @x402/mcp and @x402/evm packages, Apache-2.0) and retries the call. If not, it refuses with a clear error and signs nothing. Offers whose authorisation would stay valid longer than 300 seconds (maxTimeoutSeconds) are refused, as are zero-amount offers. Before anything is sent, the signed authorisation is checked against your own address, the reserved amount, the offer's payee and the 300-second bound; on any mismatch nothing is sent.

Payments are only ever signed for USDC on Base mainnet.

Security notes
  • The key is read only from TANOD_PRIVATE_KEY. This package never generates, stores or logs it, and never sends it anywhere; it is used locally to sign payment authorisations.
  • Use a dedicated wallet funded with a small amount (a few dollars). Do not reuse a wallet that holds real savings.
  • The caps are your safety net. Lowering them is always safe; raise them only on purpose.
  • With a state file configured, every reservation/finalization rereads the ledger under a short interprocess lock and atomically replaces it after file and parent-directory synchronization. Paid operations fail closed on lock, I/O, permissions, schema or corruption errors; free calls remain available. No best-effort reset to zero occurs. Do not delete the ledger or its .initialized marker to regain budget.
  • Amounts and limits use exact atomic USDC. Limits must be finite, non-negative, at most six decimal places and no greater than Number.MAX_SAFE_INTEGER atomic units. A malformed/unsupported offer never reaches the signer. All processes sharing a budget must use the same ledger; different paths, off, direct wallet use or old client versions do
