Install

How do I install the SSTV Decoder MCP server?

SSTV Decoder is a hosted endpoint at https://bonissystems.com/api/knox/agents/sstv-decoder/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 2 exposed · ~418 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
decode_sstv ~321

Demodulate a presented slow-scan-television (SSTV) audio recording, anchor the audio fingerprint and the decoded image hash to the Knox event chain, and return a self-authenticating receipt bundle (Knox anchor + C2PA-aligned envelope + FRE 902(13)/(14)-shape affidavit). Audio bytes are NOT retained — only the SHA-256 fingerprint and the decoded image are anchored. Bonis Systems does not capture audio on its own; the audio must be presented by the caller (a public WebSDR recording, a customer-controlled SDR capture they consent to submit, or audio they own). Phase 1 supports Martin M1 (VIS code 0x2C, 320×256 RGB). Other VIS codes return mode = 'unsupported' with detected hex. Requires a Knox Bearer API key on the Authorization header — unauthenticated calls are rejected.

NameTypeReqDescription
audioBase64stringyesBase64-encoded audio. Either a complete WAV file (RIFF/WAVE, 8/16/24-bit PCM or 32-bit IEEE float, mono or stereo, 4-192 kHz) or raw 16-bit signed little-endian mono PCM samples.
audioFormatstring–Audio container ('wav' default, or 'pcm16-mono').
captureobject–Optional capture-context metadata.
namestringyesDisplay name for the recording (max 256 chars).
sampleRateinteger–Required when audioFormat = 'pcm16-mono'.

No examples provided.

verify_sstv_decode ~97

Verify a previously anchored SSTV-decode record. Given a SHA-256 anchor hash (the payload_hash from a prior decode_sstv call), return the anchor record, predecessor hash, sequence number, and timestamp. Public — no authentication required. The verification path itself is also accessible at GET /api/knox/verify?hash=<hash>.

Common questions

What is the SSTV Decoder MCP server?

SSTV Decoder is an MCP server listed in the public MCP registry as com.bonissystems/sstv-decoder. Decode an SSTV audio recording and anchor its fingerprint and image hash to the Knox event chain. This page covers its hosted endpoint (https://bonissystems.com/api/knox/agents/sstv-decoder/mcp).

Is the SSTV Decoder MCP server safe to use?

SSTV Decoder scores 35 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the SSTV Decoder MCP server expose?

SSTV Decoder exposes 2 tools: decode_sstv, verify_sstv_decode. Their descriptions and schemas cost roughly 418 tokens of context every time the server is loaded.

Does the SSTV Decoder MCP server require authentication?

No. We connected to SSTV Decoder without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the SSTV Decoder MCP server still maintained?

SSTV Decoder is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
