"Bitcoin Cash" matching MCP servers:

Provides cryptographic truth infrastructure for AI agents, enabling them to seal content with SHA-256 and Ed25519, verify receipts, anchor them to Bitcoin via OpenTimestamps, generate citations, and audit chains of receipts.

MCP server for on-chain attestation and wallet trust profiles across 31 EVM chains and Solana. Privacy-preserving boolean verification, ECDSA-signed responses, compliance templates.

Authentication, pay-per-call metering, and signed receipts for AI agents and MCP tools using Bitcoin and Lightning Network.

Enables auditing of extracted balance sheets, income statements, and cash flow reports by reconstructing complex document tables and verifying mathematical consistency and formula balancing. It also performs cross-reference resolution and sensitive PII redaction, returning structured matrices and validation telemetry over MCP to clients like Claude Desktop, Cursor, and Windsurf.

Audits extracted balance sheets, income statements, and cash flow reports for mathematical consistency and formula balancing, reconstructing complex financial tables and resolving cross-references from document or OCR payloads. Also performs spatial layout parsing and PII redaction, returning structured matrices and validation telemetry over MCP.

Cryptographic hash generator supporting MD5, SHA1, SHA256, SHA512, and bcrypt, with pay-per-call via x402 (USDC on Base L2) – no API key or signup required.

Provides cryptographic hash and HMAC computation for text, supporting algorithms like md5, sha1, sha256, sha384, and sha512. All operations are performed locally without transmitting or storing input data.

A governed MCP server exposing 37 risk-checked tools with signed Ed25519 receipts on a Bitcoin-anchored ledger, failing closed if governance or receipt writing fails.

MCP server that vets LLM-emitted shell commands BEFORE execution — detects rm -rf nested deep in chains, package-manager glob removal (apt remove 'nvidia'), dd/mkfs filesystem destruction, chmod 777 / chown -R privilege blast, network-exfil via curl | bash, chained shutdown/reboot, git destructive ops. 30 detection rules across 8 families. Sub-second, local, free, MCP-native.

The MCP ecosystem is growing fast. Not every server on npm is safe. mcp-shield lets Claude audit any MCP server — local or from npm — before you trust it with your files, keys, and context.

This foundation-only service is intended to enable narrowly bounded, typed operations over Shayona business data, starting with an approval-bound, redacted-preview workflow for emailing customer service credentials. It is designed to keep usernames and decrypted passwords out of MCP results, previews, errors, logs, traces, and approval state.

Resolves an authenticated MCP HTTP request to an existing, enabled Frappe User, enabling downstream consumers to run request-scoped permission checks.
