"Understanding Base64 Encoding for Images" matching MCP tools:

• upload_dataset

  GoldenMatch

  Upload a local file's bytes to the server and get back a server-side path to reuse across other tools (analyze_data, auto_configure, agent_deduplicate, ...). No hosting needed. Send base64 (default) or raw text via `encoding`. Uploaded files are ephemeral scratch, reaped after GOLDENMATCH_MCP_UPLOAD_TTL (default 24h); re-upload if you need a path older than that. Max size GOLDENMATCH_MCP_MAX_UPLOAD_BYTES (default 64MB) -- above it, pass a public http(s) URL as file_path instead.

• add_files

  vibedeploy

  Append files to an open staging session. Call as many times as needed; commit_deploy applies them all at once. Validates path/extension/encoding on every call so a bad file fails fast. Same 500 MB cap as single-call deploys, but cumulative across the session. LARGE TEXT FILES: a file that looks too big to inline (100-250 KB of HTML/CSS/JS) usually still fits in ONE call — gzip it locally, base64 the result, send with encoding:'gzip+base64' (text compresses 3-5×, so ~250 KB of source ≈ ~70 KB on the wire). Prefer that over add_file_chunk: one call, no ordering hazards. Only chunk when a single file exceeds ~250 KB of source even after gzip, or when you have no way to gzip locally. If your environment can run shell but can't reach this host, gzip+base64 via add_files is the fastest path; if it CAN reach this host, begin_deploy's uploadUrl (tarball POST, 100 MB) beats everything.

• convert_html_to_pdf

  Sats4AI - Bitcoin-Powered AI Tools

  Convert HTML or Markdown to a pixel-perfect PDF. Returns JSON: { url } — a temporary download URL (valid ~1 hour). Great for generating invoices, reports, receipts, or formatted documents programmatically. Supports full HTML/CSS including tables, images (base64 or URL), and inline styles. For Markdown input, set format='markdown'. 50 sats per conversion. Use convert_file instead for converting existing files between formats (e.g., DOCX→PDF). Pay per request with Bitcoin Lightning — no API key or signup needed. Requires create_payment with toolName='convert_html_to_pdf'.

• encode_decode

  mcp

  Use this when you need to encode or decode text and want multi-byte and entity edge cases handled correctly rather than doing it by hand. Deterministic: same input, same output. The mode selects the operation: url-encode/url-decode (percent-encoding), html-encode/html-decode (entity table plus numeric character references), base64-encode/base64-decode (UTF-8 safe; decode tolerates URL-safe alphabet, whitespace, and missing padding), and unicode-encode/unicode-decode (\uXXXX and \u{...} escapes for non-ASCII). Every mode returns the same shape: {mode, output}. Example: mode base64-encode, text "héllo" -> output "aMOpbGxv".

• pentest_encode

  pentest-mcp-server

  Transform a payload string through one or more encoding layers for bypass research during authorized testing. Accepts a chain of encodings applied in order (e.g., ["unicode", "url", "base64"] applies Unicode → URL-encode → base64). Returns the transformed payload with a step-by-step decoding explanation: how a WAF or server would decode each layer, and why the combined encoding might bypass a specific filter. Use to understand filter bypass mechanics in an authorized engagement and to confirm that a target's decoding pipeline matches an expected bypass path. Payloads are transformed mathematically — no live probing occurs.

• clipform_search_media

  Clipform

  Search images or stock video clips. Pass one query or many (max 10) - multiple queries run in one call instead of separate tool calls. Use results to feed into clipform_generate_video for narrated slideshow videos, or upload directly as still images via clipform_upload_media_asset then clipform_attach_node_media. All results are pre-cleared for commercial use. Results include a description (alt text where the provider has it) - use it to pick visually distinct images. Example: { queries: [{ query: "saturn rings" }, { query: "mars surface", count: 3 }] } returns portrait images for both.

  Connector

• document.extract_text

  api

  Extract plain text from a PDF or image (base64-encoded). Use when you need raw text for downstream AI analysis (summarization, claim checking, structured extraction). For documents at a public URL, use url.extract instead (no base64 encoding needed). Returns: { pages: number, text: string } Example prompts: - "Extract the text from this scanned contract so I can search it." - "Give me the raw text from this PDF document." - "OCR this image and return the text content."

• add_file_chunk

  vibedeploy

  Stream a single file across multiple calls when its content exceeds the per-MCP-call output budget. LAST RESORT — try these first: (1) add_files with encoding:'gzip+base64' fits ~250 KB of text source in ONE call (gzip locally, base64, send — no chunking, no ordering hazards); (2) begin_deploy's uploadUrl takes a 100 MB tarball in one HTTP POST if your sandbox can reach mcp.vibedeploy.be; (3) deploy_from_url if the files are fetchable from a public URL. Only chunk when none of those work. When you DO chunk, gzip+base64 each chunk too — it quadruples the source bytes per chunk. Mark the first chunk with isFirst=true (truncates + mkdir) and the last with isLast=true (returns assembled size). Send chunks for the same path serially — concurrent chunks interleave and corrupt the file.

• create_inference

  Retro Diffusion Pixel Art MCP

  Generate images using the public /v1/inferences endpoint. For the highest quality prefer RD Pro styles (rd_pro__*); they support reference_images for character/style consistency. For animation styles prefer start_inference_job + get_inference_job instead — animations are long-running. Use `input_image` for the main source image, `reference_images` for extra per-inference guidance, and `style_reference_images` only on create_user_style/update_user_style. The response excludes raw base64 image payloads to keep MCP outputs compact.

  Connector

• upload_image

  BetaFinds

  Upload an image (logo or screenshot) for create_startup. Pass the file content as base64 (data is base64 only, no data: prefix). Returns a url to pass into create_startup. Max 2 MB; formats: JPEG, PNG, WebP, GIF.

  Connector

• update_site

  vibedeploy

  Patch or replace files on an existing site. Defaults to patch mode: only the listed files change; everything else stays. Pass mode:'replace' to wipe-and-replace the whole site (the legacy behaviour, surfaced explicitly so it can't happen by accident). Use `delete: [paths]` in patch mode to remove specific files without wiping the rest. Use `dryRun: true` to preview the diff before committing. LARGE FILES: a 100-250 KB text file fits in one call with encoding:'gzip+base64' (gzip locally, base64 the result) — prefer that over begin_deploy + add_file_chunk streaming. Errors if the site does not exist.

• upload_file

  mcp

  Host a small file by sending its bytes inline as base64. Prefer create_upload_url instead: inline base64 is slow and costly above roughly 100KB. For a user's own files only. Needs a FileToUrl Developer API key.
