## Description
One MCP, many parsers. Routes between markitdown, Docling, and LlamaParse. Plus an interpret tool…

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "one-mcp-many-parsers": {
    "command": "npx",
    "args": ["-y","one-mcp-many-parsers"]
  }

One MCP, many parsers. Default markitdown (free, fast, MIT). Escalate to Docling (table-heavy, scanned PDFs) or LlamaParse (cloud, BYOK) when markitdown's quality isn't enough. Plus an `interpret` tool that pipes parsed markdown into Claude for "summarize / extract X" so you stop juggling parsers and anthropic skills.

## Install

Open Claude Code, paste:

    /plugin marketplace add adelaidasofia/parse-mcp
    /plugin install parse-mcp@parse-mcp

<details><summary>Legacy install</summary>

Manual install (pre-plugin-marketplace). See `SETUP.md` for full details.

```bash
pip3 install --break-system-packages -r requirements.txt
pip3 install --break-system-packages 'markitdown[pdf,docx,pptx,xlsx]'
```

Then register the server in your client's `.mcp.json`:

```json
{
  "mcpServers": {
    "parse": {
      "command": "python3",
      "args": ["/absolute/path/to/parse-mcp/server.py"]
    }
  }
}
```

</details>

## Tools

| Tool | What it does |
|---|---|
| `parse(source, backend?, hints?)` | File path or http(s) URL to markdown. Router picks backend, falls back on empty/error. Returns markdown plus a chain of every backend attempted. |
| `parse_url(url, backend?)` | Shortcut for HTTP(S) inputs. Same return shape as `parse`. |
| `parse_to_vault(source, vault_folder?, backend?, overwrite?)` | Parse + write the result as a markdown note in the vault. Default folder: `<VAULT_ROOT>/📥 Inbox/Converted/`. Frontmatter records source, format, backend, latency, bytes_in. Replaces the standalone `markitdown_to_vault.py` shell script. |
| `interpret(source, instruction, backend?, model?, max_tokens?)` | Parse first, then ask Claude over the parsed markdown. Cache hits reuse parsed text for free input tokens. |
| `list_backends()` | Which backends are installed + which are missing. Diagnostic. |
| `benchmark(source)` | Run every available backend on the same input. Compare latency + output side by side. |
| `chunk_text(text, doc_type?, target_tokens?, max_tokens?, min_tokens?)` | Chunk parsed markdown into retrieval-ready pieces using a doc-type-aware chunker. `doc_type="auto"` (default) runs structural detection and picks one of paper / book / manual / qa / resume / table / default. Each chunker honors document shape (e.g., `paper` keeps the abstract whole; `manual` never merges across numbered sections; `qa` pairs each question with its answer). Returns chunks + the resolved doc_type. See `chunkers/` package. |
| `detect_doc_type(text)` | Diagnostic. Run structural heuristics over markdown and return the doc_type that `chunk_text` would pick. |

## Backends (priority order)

1. **markitdown** (default, MIT, base install). PDF, DOCX, PPTX, XLSX, HTML, CSV, JSON, XML, EPub, ZIP. Fast, deterministic.
2. **docling** (optional, `pip install docling`). Best for complex tables (97.9% on benchmark) + scanned PDFs. Downloads model weights on first run.
3. **llamaparse** (optional, BYOK, `pip install llama-cloud-services` + `LLAMA_CLOUD_API_KEY`). Cloud, cleanest output on visually-complex PDFs.

## Routing strategy

- `parse(source)` with no `backend` arg: router picks based on file format, falls back if backend errors or returns empty.
- `parse(source, backend="docling")`: force a specific backend, no fallback. Diagnostic mode.
- Unavailable backends are skipped (logged in the chain), never errored.

## Parse-fidelity eval

The routing table above used to be a guess. `tests/eval/` turns it into data: a
synthetic fixture corpus (16 documents across digital PDF, scanned/image-only
PDF, table-heavy, multi-column, and raster image classes) with derived
ground-truth markdown, scored against each backend's output on three
OmniDocBench / PubTabNet metrics — text edit distance, table **TEDS**
(tree-edit-distance similarity), and reading-order. All scores are quality in
[0, 1], higher is better.

Headline result (full table: [`tests/eval/parse_fidelity_matrix.md`](tests/eval/parse_fidelity_matrix.md)):

| doc-class | markitdown (text) | docling (text) |
|---|---|---|
| digital_pdf | 0.95 | 0.97 |
| table_heavy | 0.93 | 0.89 |
| scanned_pdf | **0.00** | 0.87 |
| image | **0.00** | 0.90 |
| multicolumn | 0.35 | 1.00 |

markitdown is great on clean digital text and digital tables (free, fast,
deterministic) but has **no OCR** — it scores zero on scanned PDFs and images —
and it interleaves multi-column layouts. docling wins every class via OCR +
layout analysis, at the cost of model-weight downloads. That is the evidence
behind the format-preference chain (escalate image/scanned/multi-column to
docling first).

Run it:

```bash
pip install docling                      # the escalation backend under test
python tests/eval/generate_fixtures.py   # rebuild the corpus (needs fpdf2 + Pillow)
make eval                                # -> parse_fidelity_matrix.{md,json}
```

The matrix records its **provenance** (backend + python versions + a fixture-set
hash), so a stale result is visible — regenerate with `make eval` whenever a
parse backend is upgraded or retuned. It also reports **median latency** per
backend (the cost axis): the highest-fidelity backend (docling) is far slower
than the default, so the router escalates to it rather than defaulting to it.

The scorer's metric tests are pure-Python and backend-free, so `pytest tests/`
gates them in CI with only the base (markitdown) install — a routing regression
that breaks the "markitdown has no OCR" assumption fails the build.

## Architecture

FastMCP v3.2.3+, stdio transport, Python 3.13+. Registered in `[VAULT_ROOT]/.mcp.json`. No daemons, no listeners, no model weights downloaded by default.

See `SETUP.md` for install + per-backend opt-in.

## Telemetry

This plugin sends a single anonymous install signal to `myceliumai.co` the first time it loads in a Claude Code session on a given machine.

**What is sent:**
- Plugin name (e.g. `slack-mcp`)
- Plugin version (e.g. `0.1.0`)

**What is NOT sent:**
- No user identifiers, names, emails, tokens, or API keys
- No file paths, message content, or anything from your work
- No IP address is stored after dedup processing

**Why:** Helps the maintainer know which plugins people actually install, so attention goes to the ones that get used.

**Opt out:** Set the environment variable `MYCELIUM_NO_PING=1` before launching Claude Code. The hook will skip the network call entirely. Already-pinged installs leave a sentinel at `~/.mycelium/onboarded-<plugin>` — delete it if you want to reset state.
