Anlyon alternative
6 of these tools change something. Run those as governed actions.
Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.
Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Changes things 6Claude Code: ask
add_columnsAdd columns to a draft you run, such as a blank one a person started.Reads text others writeNo findings
Why it is in this group
- The name "add_columns" says "add": a word for a change.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it Add columns to a draft you run, such as a blank one a person started. Returns the new column ids for fill_cells. Needs a token.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: false
- openWorldHint: true
add_rowsAdd rows to a draft you run, as you find what belongs in it.Reads text others writeNo findings
Why it is in this group
- The name "add_rows" says "add": a word for a change.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it Add rows to a draft you run, as you find what belongs in it. A name it already has is skipped. Needs a token.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: false
- openWorldHint: true
check_claimTest a statement against one cell, such as whether a value in a draft or an answer is right.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it Test a statement against one cell, such as whether a value in a draft or an answer is right. The verdict is `matches`, `differs` (with what the source states), `disputed` (sources disagree, see `conflicts`) or `unknown` (no acceptable source stated it, so say so). It compares values and doesn't judge meaning, so read the quote before relying on a text verdict. Use list_tables and get_table to find the cell first.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
create_tableMake a private draft table, ready to fill.Reads text others writeNo findings
Why it is in this group
- The name "create_table" says "create": a word for a change.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it Make a private draft table, ready to fill. Only `title`, `columns` and `rows` are needed now, but give `question`, `scope`, and a `rule` for each column if you can: a person has to supply them before publishing. Returns the column ids fill_cells needs, and the sheet's link, so tell your person to open it and watch it fill. Needs a token.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: false
- openWorldHint: true
fill_cellsFill up to 25 cells of a draft you run.Reads text others writeNo findings
Why it is in this group
- The name "fill_cells" says "fill": a word for a change.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it Fill up to 25 cells of a draft you run. Each cell gives `value`, `source` and `quote`, where the quote is word for word from the source and states the value; each is checked and the page opened before it's saved. If no acceptable source states it, give `checked` with the pages you read instead of a value, and add `none_stated` only if you read the whole source and it has no such value. Bad cells come back with a reason and don't stop the rest. Needs a token.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: false
- openWorldHint: true
propose_changeSuggest a new value for a cell, with its proof.Reads text others writeNo findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it Suggest a new value for a cell, with its proof. The quote must be word for word from the source and state the value. The owner reviews it before anything changes. Needs a token sent as a Bearer token.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: false
- openWorldHint: true
Only reads 3Show 3 read-only tools
get_cellThe evidence for one value: the source, the exact quote, what kind of source it is and when it was read.No findings
Why it is in this group
- The name "get_cell" says "get": a word for reading.
Description, as the server wrote it The evidence for one value: the source, the exact quote, what kind of source it is and when it was read. For a missing value, where we looked, and `absent` means the source was read and gives no such value. `url` is the cell's lasting address, showing its proof, for citing. `confirmed` says how a second reader backed it up, and without it the value has been read once. `conflicts` lists sources that state something else, `history` lists past values, and `watch` says whether the quote was still on its page at the last check.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
get_tableRead a table: its scope, its columns with the rule for each, and its rows.Reads private dataNo findings
Why it is in this group
- The name "get_table" says "get": a word for reading.
What it can reach
- private-dataThe name "get_table" says "get" and "table": it reads databases.
- private-dataThe description's first sentence says "read" and "table": it reads databases.
Description, as the server wrote it Read a table: its scope, its columns with the rule for each, and its rows. A null value means no acceptable source stated it.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
list_tablesFind tables in the library.Reads private dataNo findings
Why it is in this group
- The name "list_tables" says "list": a word for reading.
What it can reach
- private-dataThe name "list_tables" says "list" and "table": it reads databases.
- private-dataThe description's first sentence says "find" and "table": it reads databases.
Description, as the server wrote it Find tables in the library. Each result gives its slug, the question it answers, its size and when it was last read.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
Exfil surface
Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.
No private-data, untrusted-input, outbound path in this server alone: no tool is tagged outbound.
- Reads private data2
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write5
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out0
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

The endpoint served tools/list without credentials, and the list has 7 tools that change things (7 write). Whether a call also works without credentials was not tested: tools are never called.
What this check looks forMatched text
https://skeletable.com/mcp: tools/list returned 10 tools to an anonymous client, including check_claim (write), export_table (write), propose_change (write), create_table (write), add_columns (write) and 2 more
Findings
Matches of fixed checks, with the text they matched.
No check matched anything in these tool definitions. That is not a safety guarantee.
History
Changes to its tool definitions and to its remote endpoint, newest first.
No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.
